In the state where the left front side sliding member 50 is assembled to the left front side portion of the sunshade 40, the sliding member main body 50 a of the left front side sliding member 50 includes the proximal side wall portion 51 a and the lower side wall portion of the upper side wall 51. 53, the front end portion of the left thin edge portion 40d of the shade layer 40a is sandwiched.

  At this time, the sliding member main body 50a of the left front sliding member 50 has a rear side on the front end portion of the left side vicinity portion 41 of the thick central portion 40c of the shade layer 40a at the tip side wall portion 51b of the upper side wall 51. Abuts uniformly.

  When the left rear sliding member 50 is assembled to the left rear portion of the sunshade 40, the sliding member body 50 a of the left rear sliding member 50 is the proximal side wall portion 51 a of the upper side wall 51. The rear end of the left thin edge 40d of the shade layer 40a is sandwiched between the lower wall 53 and the lower wall 53. At this time, the sliding member main body 50a of the left rear side sliding member 50 is positioned at the rear end portion of the left side vicinity portion 41 of the thick central portion 40c of the shade layer 40a at the front end side wall portion 51b of the upper side wall 51. Abuts uniformly from the back side.

  Further, in a state where the right rear sliding member 50 is assembled to the right rear side portion of the sunshade 40, the sliding member main body 50 a of the right rear sliding member 50 is the base end side wall portion 51 a of the upper side wall 51. The rear end portion of the right thin edge portion 40d of the shade layer 40a is sandwiched between the lower wall 53 and the lower wall 53. At this time, the sliding member main body 50a of the right rear sliding member 50 is arranged at the rear end portion of the right side vicinity portion 41 of the thick central portion 40c of the shade layer 40a at the tip side wall portion 51b of the upper side wall 51. Abuts uniformly from the back side.

  Here, in each sliding member 50 configured as described above, the grounds for configuring the upper side wall 51 of the sliding member main body 50a as described above will be described.

  The conventional upper side wall corresponding to the upper side wall 51 has the following configuration. That is, similar to the upper side wall 51, the conventional upper side wall extends from the upper edge of the connecting wall 52 so as to be bent in an L shape, and the conventional upper side wall extends from the inner surface of the connecting wall 52. The extension length is shorter than the proximal end side wall portion 51a of the upper side wall 51, and is a predetermined length E (for example, E = 8.5 (mm)) (see FIG. 6).

  For this reason, four conventional sliding members having the upper side wall replacing the upper side wall 51 are prepared as conventional sliding members instead of the sliding member 50. With these conventional sliding members, the sunshade is prepared. Assuming that 40 is supported, the upper side wall of the related art, for example, in the case of a sliding member corresponding to the right front side sliding member 50, is in contact with the front end of the right thin edge 40d of the shade layer 40a. It does not reach the front end portion of the right side vicinity portion 41 of the thick central portion 40c.

  The same applies to the remaining conventional sliding members. The configuration of the conventional sliding member is the same as that of the sliding member 50 except for the conventional upper side wall. Accordingly, components other than the upper wall of the conventional sliding member are denoted by the same reference numerals as those of the components other than the upper wall 51 of the sliding member 50. Further, the material for forming the conventional sliding member is the same as the material for forming the sliding member 50.

  Therefore, when the left and right thin edge portions 40d of the shade layer 40a are supported by the left and right rail members 30a through the corresponding conventional sliding members at the front and rear ends, external force is applied to the sunshade 40. On the other hand, when given in the direction of pulling downward through the handle 40f, the sunshade 40 tends to bend downward according to the strength of the external force.

  At this time, the thick central portion 40c is different from the left and right thin edge portions 40d supported in the lateral U-shaped groove portions 34 of the left and right side guide rail devices 30a with respect to the downward pulling force. Since the shade layer 40a can be freely bent, first, the shade layer 40a is bent downward together with the skin layer 40b at the thick central portion 40c with reference to the left and right thin edge portions 40d.

  Here, in the shade layer 40a, the maximum thickness of the thick central portion 40c is smaller than the thickness of the left and right thin edge portions 40d, and the thickness of the portion 41 near both left and right sides of the thick central portion 40c. Is closer to the thickness of the left and right thin edge portions 40d. On the other hand, the conventional material for forming the sliding member is harder than the material for forming the sunshade 40 as described above.

  In addition, the left and right thin edge portions 40d of the shade layer 40a are firmly sandwiched between the conventional upper side wall and the lower side wall 53 of each conventional sliding member at both front and rear end portions thereof. Thus, even if the thick central portion 40c bends downward, the left and right thin edge portions 40d are not displaced from the conventional upper side wall and the lower side wall 53 in each conventional sliding member. The conventional upper side wall and the lower side wall 53 are firmly sandwiched. This is true regardless of the strength of the external force.

  For this reason, when the thick central portion 40c is bent downward as described above, the left and right thin edge portions 40d are bent downward by the thick central portion 40c at the boundary with the thick central portion 40c. As a result, they are pulled together and integrated with each of the conventional sliding members, and disengage from the insides of the horizontal U-shaped groove portions 34 of the left and right side guide rails 30a while shifting in the bending direction of the thick central portion 40c.

  At this time, each conventional sliding member has an opening lower end portion (a tip end portion of the lower rail portion 32) of each lateral U-shaped groove portion 34 of each lateral guide rail 30a at the inner and outer side rib portions 55a and 55b. ) In accordance with the downward deflection of the thick central portion 40c, it is inclined in the downward deflection direction of the thick central portion 40c from the conventional upper wall side.

  In such a process, since the right and left thin edge portions 40d are thinner than the central thick portion 40c as described above, the lower side rib portions 55a and 55b of the conventional sliding members as described above are below. Based on the boundary with the thick central portion 40c as a reference with the tip of the side rail portion 32 in contact with each other, each of the conventional slides according to the downward deflection toward the thick central portion 40c described above. It bends together with the conventional sliding members in the direction of inclination of the moving member.

  Therefore, although depending on the strength of the external force, the shade layer 40a eventually bends or bends along with the skin layer 40b at the boundary between the central thick portion 40c and the left and right thin edge portions 40d. Therefore, there is a possibility that the original role as a sunshade cannot be achieved.

  Therefore, in the first embodiment, the upper side wall 51 of each sliding member 50 is configured to have the base end side wall part 51a and the front end side wall part 51b as described above, and the center in the shade layer 40a described above. The bending phenomenon and the bending phenomenon at the boundary part between the thick part 40c and the right and left thin edge parts 40d are prevented in advance.

  In the first embodiment configured as described above, the sunshade device SD is assembled to the left and right guide rails 30a so as to be slidable in the front-rear direction, and as shown in FIG. To do.

  In such a state, in the sunshade device SD, as shown in FIG. 9, the right front side sliding member 50 is in the sliding member main body 50a, and the right side guide rail 30a has a transverse U-shaped groove 34 in the transverse section. It is slidably accommodated inside. For this reason, the sliding member main body 50a is guided to the right side through the inner and outer spring portions 54a and 54b and the inner and outer rib portions 55a and 55b at the front end portions of the base wall portion 51a and the lower wall 53 of the upper side wall 51. The upper rail portion 31 and the lower rail portion 32 of the rail 30a are sandwiched between the front end portions thereof.

  At this time, in the right front side sliding member 50, the sliding member main body 50a receives a repulsive force based on the contact with the upper rail portion 31 of the inner and outer side spring portions 54a and 54b and is pressed downward, and the inner and outer side ribs The protruding end portions of the portions 55a and 55b are firmly in contact with the inner surface of the lower side wall 53.

  As a result, the right thin edge 40d of the shade layer 40a is formed between the upper rail portion 31 and the lower rail portion 32 of the right guide rail 30a at the front end portion thereof. It is supported by the sliding member main body 50a so as to extend along the extending direction of the lower rail portion 32.

  At this time, the upper side wall 51 of the sliding member main body 50a comes into contact with the front end portion of the right thin edge portion 40d from the back side (the upper side in FIG. 9) at the front end portion of the proximal end side wall portion 51a. At the front end portion of the side wall portion 51b, the front end portion of the right side vicinity portion 41 of the thick central portion 40c abuts from the back side (the upper side in FIG. 9).

  The left front sliding member 50 is slidably accommodated in the lateral U-shaped groove 34 of the left guide rail 30a by the sliding member main body 50a. For this reason, the sliding member main body 50a is provided with a left guide rail via inner and outer side spring portions 54a and 54b and inner and outer side rib portions 55a and 55b at the base end side wall portion 51a of the upper side wall 51 and the front end portion of the lower side wall 53. The upper rail part 31 and the lower rail part 32 of 30a are clamped between the respective front end parts.

  At this time, in the left front side sliding member 50, the sliding member main body 50a receives a repulsive force based on the contact with the upper rail portion 31 of the inner and outer side spring portions 54a and 54b and is pressed downward, and the inner and outer side ribs The protruding end portions of the portions 55a and 55b are firmly in contact with the inner surface of the lower side wall 53.

  As a result, the left thin edge portion 40d of the shade layer 40a is, at its front end portion, between the upper rail portion 31 of the left guide rail 30a and the front end portions of the lower rail portion 32. It is supported by the sliding member main body 50a so as to extend along the extending direction of the lower rail portion 32.

  At this time, the upper side wall 51 of the sliding member main body 50a is in contact with the front end portion of the left thin edge portion 40d from the back side at the base end side wall portion 51a, and at the distal end side wall portion 51b, the thick central portion 40c. Is in contact with the front end portion of the left side vicinity portion 41 from the back side.

  The right rear sliding member 50 is slidably accommodated in the lateral U-shaped groove 34 of the right guide rail 30a by the sliding member main body 50a. For this reason, the sliding member main body 50a is inserted into the right side through the inner and outer side spring parts 54a and 54b and the inner and outer side rib parts 55a and 55b at the rear end parts of the base side wall part 51a and the lower side wall 53 of the upper side wall 51. The upper and lower rail portions 31 and 32 of the guide rail 30a are sandwiched between the rear end portions thereof.

  At this time, in the right rear side sliding member 50, the sliding member main body 50a receives a repulsive force based on the contact with the upper rail portion 31 of the inner and outer side spring portions 54a and 54b and is pressed downward, and both the inner and outer sides are pressed. The ribs 55a and 55b are in firm contact with the inner surface of the lower side wall 53 at the protruding end portions.

  Thus, the right thin edge 40d of the shade layer 40a is located between the upper rail 31 and the lower rail between the upper rail 31 and the lower rail 32 of the right guide rail 30a at the rear end. It is supported by the sliding member main body 50 a so as to extend along the extending direction of the portion 32.

  At this time, the upper side wall 51 of the sliding member main body 50a is in contact with the rear end portion of the right thin edge portion 40d from the back side at the rear end portion of the base end side wall portion 51a, and the rear end of the front end side wall portion 51b. This part is in contact with the rear end portion of the right side vicinity portion 41 of the thick central portion 40c from the back side.

  The left rear sliding member 50 is slidably accommodated in the groove 34 with a transverse cross section of the left guide rail 30a by the sliding member main body 50a. For this reason, the sliding member main body 50a is located on the left side via the inner and outer side spring portions 54a and 54b and the inner and outer side rib portions 55a and 55b at the rear end portions of the base side wall portion 51a and the lower side wall 53 of the upper side wall 51. The upper and lower rail portions 31 and 32 of the guide rail 30a are sandwiched between the rear end portions thereof.

  At this time, in the left rear side sliding member 50, the sliding member main body 50a receives a repulsive force based on contact with the upper rail portion 31 of the inner and outer side spring portions 54a and 54b, and is pressed downward, so The ribs 55a and 55b are in firm contact with the inner surface of the lower side wall 53 at the protruding end portions.

  Accordingly, the left thin edge portion 40d of the shade layer 40a is located between the upper rail portion 31 and the lower rail portion of the left guide rail 30a between the upper rail portion 31 and the lower rail portion 32 at the rear end portion. It is supported by the sliding member main body 50 a so as to extend along the extending direction of the portion 32.

  At this time, the upper side wall 51 of the sliding member main body 50a is in contact with the rear end portion of the left thin edge portion 40d from the rear side at the rear end portion of the base end side wall portion 51a, and the rear end of the front end side wall portion 51b. This part is in contact with the rear end part 41 on the left side of the thick central part 40c from the back side.

  As described above, the left front side, the right front side, the left rear side, and the right rear side of the sliding members 50 are respectively connected to the left and right side guide rails 30a between the left and right side front and rear ends of the sunshade 40 by the respective sliding member bodies 50a. Are supported in both front and rear end portions of the lateral U-shaped groove portion 34. Here, the front and rear end portions of the left and right thin edge portions 40d of the shade layer 40a are respectively connected to the corresponding proximal end side wall portions 51a and the lower side in the transverse U-shaped groove portions 34 of the corresponding sliding member main body 50a. It is firmly sandwiched between the side walls 53 so as not to escape.

  In other words, in the sunshade device SD, the sunshade 40 is formed in the lateral U-shaped groove 34 of the left guide rail 30a through the left front side, right front side, left rear side, and right rear side sliding members 50. The front and rear ends and the right and left guide rails 30a are supported in the front and rear ends of the lateral U-shaped groove 34 in the cross section. At this time, since there is no external force acting on the sunshade 40, the sunshade 40 is maintained in its original state without being bent in the vertical direction (see FIGS. 3 and 9).

  In such a state, when the occupant M1 holds the handle 40f with his / her hand and moves the sunshade 40 to further open or close the window W by the sunshade device SD, the occupant M1 erroneously or If the handle 40f is pulled unconsciously, the downward pulling force acts on the sunshade 40 as an external force.

  Therefore, when the downward pulling force acts on the sunshade 40 as an external force as described above, the thick central portion 40c of the shade layer 40a is not directly supported by each sliding member 50 from the lower side, Unlike the thin edge portions 40d on both the left and right sides, it can bend freely with respect to the downward pulling force. For this reason, first, the shade layer 40a is first formed at the thickness center portion 40c by the upper and lower rail portions 31 and 32 of the left and right guide rails 30a as shown in FIG. The left and right thin edge portions 40d sandwiched between the portions are bent so as to be bent downward together with the skin layer 40b.

  However, the left and right thin edge portions 40d of the shade layer 40a are firmly sandwiched between the base end side wall portions 51a and the lower side walls 53 of the corresponding sliding member main bodies 50a at the respective front and rear end portions thereof. ing.

  Therefore, when the shade layer 40a is bent downward together with the skin layer 40b at the thick central portion 40c as described above, the left and right thin edge portions 40d exemplify the sliding member bodies 50a in FIG. While rotating in the direction (counterclockwise in the figure), the thick central portion 40c is pulled downward together with each sliding member main body 50a as it is bent downward.

  At this time, as shown in FIG. 10, each sliding member main body 50a abuts the protruding end portion of the inner rib portion 55a on the inner surface of the lower rail portion 32 of the left and right guide rails 30a and the outer spring. In the direction of escaping from the horizontal U-shaped groove 34 along the lateral cross section along with the left and right thin edge portions 40d in the direction shown in FIG. 10 from the position shown in FIG. Rotate.

  However, in the first embodiment, as shown in FIG. 9, each sliding member main body 50a is located near the left and right sides of the thick central portion 40c of the shade layer 40a at the tip side wall portion 51b of the upper side wall 51. The front and rear end portions of 41 are uniformly in contact from the back side.

  In addition, as described above, the shade layer 40 has the corresponding proximal end side wall 51a and the lower side wall 53 in the corresponding sliding member main body 50a at the respective front and rear end portions of the left and right thin edge portions 40d. In between, it is firmly clamped together with the skin layer 40b so that it cannot escape.

  Moreover, as described above, each sliding member 50 is formed of a resin material that is harder than the forming material of the sunshade 40 over the whole, and the upper side wall 51 of each sliding member 50 is formed as a whole. Thus, it is formed to a thickness that does not deform due to an external force applied to the sunshade 40.

  Therefore, as described above, each sliding member main body 50a causes the protruding end portion of the inner rib portion 55a to abut the inner surface of each lower rail portion 32 of the left and right guide rail 30a as illustrated in FIG. When the left and right thin edge portions 40d of the shade layer 40a are rotated in the direction of escaping downward from the lateral U-shaped groove portions 34 together with the left and right thin edge portions 40d, the left and right thin edge portions 40d are as illustrated in FIG. The upper side wall 51 and the distal end side wall part 51a as described above and the distal end are not folded into the right and left side neighboring part 41 from the upper side to the lower side at the boundary part of the left and right side neighboring part 41 of the thick central part 40c. It can be satisfactorily maintained under an integral configuration with the side wall 51b.

  In other words, the upper side wall 51 of each sliding member main body 50a has an integral configuration of the base end side wall portion 51a and the distal end side wall portion 51b, and is adjacent to the left and right sides of the thick central portion 40c of the left and right thin edge portions 40d. The bending from the upper side with respect to the site | part 41 can be prevented beforehand based on the inclination-angle of the front end side wall part 51b with respect to the base end side wall part 51a.

  Therefore, if the passenger | crew M1 stops the downward pull with respect to the handle 40f mentioned above, the sunshade 40 can return to the original shape shown in FIG. 9 with the elasticity. Therefore, if the occupant M1 moves the sunshade 40 without pulling the handle 40f downward, the window W can be closed or opened.

  Further, since the downward pulling force with respect to the sunshade 40 is too strong, each sliding member main body 50a has an inner rib portion 55a as shown in FIG. 11, and each lower rail portion of the left and right guide rails 30a. Even if a situation occurs in which the front end of the extended portion 32 is detached from the lateral U-shaped groove 34 and the sunshade 40 has a thickness of the left and right thin edge portions 40d of the shade layer 40a as described above. With the sliding members 50, no damage is caused by bending downward at the central side portion of the thick central portion 40c while preventing the bending from the upper side to the lower side with respect to the left and right side neighboring portions 41 of the central portion 40c. Can be escaped from each lateral U-shaped groove 34 of the left and right guide rails 30a.

Therefore, the sunshade device SD can play the original role again by supporting the sunshade 40 again with the sliding members 50 on the left and right guide rails 30a.
(Second Embodiment)
FIG. 12 shows a main part of the second embodiment of the present invention. In the second embodiment, in the sliding member main body 50a of the right front side sliding member 50 described in the first embodiment, a lower side wall 56 is employed instead of the lower side wall 53 (see FIG. 6). Yes.

  The lower side wall 56 is obtained by further extending the lower side wall 53 described in the first embodiment, and the lower side wall 56 is bent in an L shape from the lower edge of the connecting wall 52 to the same side as the upper side wall 51. Thus, it is extended with the same extension length as the upper side wall 51. In the second embodiment, in the left front sliding member 50, the left rear sliding member 50, and the right rear sliding member 50 described in the first embodiment, the lower wall 56 is the lower wall. Instead of 53, the same structure as the lower side wall 56 of the sliding member main body 50a of the right front side sliding member 50 is adopted. Other configurations are the same as those in the first embodiment.

  In the second embodiment configured as described above, for example, when the right front side sliding member 50 is taken as an example, the lower side wall 56 is on the same side as the upper side wall 51 from the lower edge of the connecting wall 52 as described above. It is extended by the same extension length as the said upper side wall 51 so that it may be bent in a L shape.

  For this reason, the right front sliding member 50 includes the right thin edge portion 40d of the shade layer 40a and the front end portions of the right side vicinity portion 41 described above in the first embodiment, as well as the front wall portions 51 and the lower side walls 56 thereof. Both right front end portions of the skin layer 40b corresponding to both front end portions are sandwiched.

  In each of the remaining left front sliding member 50, right rear sliding member 50, and left rear sliding member 50, the lower side wall 56 extends from the lower edge of the connecting wall 52 to the same side as the upper side wall 51. It is extended by the same extension length as the said upper side wall 51 so that it may be bent in the shape of a character.

  Therefore, among the left front sliding member 50, the right rear sliding member 50, and the left rear sliding member 50, the left front sliding member 50 has the upper side wall 51 and the lower side wall 56, and the left thin edge of the shade layer 40a. Both the front end portions of the portion 40d and the left side vicinity portion 41 and the left front end portion of the skin layer 40b corresponding to both front end portions are sandwiched.

  Further, the right rear sliding member 50 has the upper side wall 51 and the lower side wall 56, the right thin edge portion 40d of the shade layer 40a, the rear end portions of the right side vicinity portion 41, and the skin corresponding to these both rear end portions. The left rear sliding member 50 sandwiches both the right rear end portions of the layer 40b, and the left thin edge portion 40d and the left side vicinity portion 41 of the shade layer 40a with the upper side wall 51 and the lower side wall 56 thereof. Both the rear end portion and the left rear end portion of the skin layer 40b corresponding to both the rear end portions are sandwiched.

  Therefore, as in the first embodiment, when the occupant M1 applies a downward pulling force to the sunshade 40 as an external force, each sliding member main body 50a has the upper side wall 51 and the lower side wall 56 of the upper side wall. 51, as described in the first embodiment, the upper side of the thick central portion 40c of the right and left thin edge portions 40d with respect to the left and right side neighboring portions 41 with the proximal end side wall portion 51a and the distal end side wall portion 51b. Can be prevented in advance from the inclination angle of the distal end side wall portion 51b with respect to the proximal end side wall portion 51a described above.

  On the other hand, each sliding member main body 50a has a thick central portion of the left and right thin edge portions 40d by the upper side wall 51 described in the first embodiment at the lower side wall 56 of the upper side wall 51 and the lower side wall 56. In the prevention of the bending from the upper side to the lower side with respect to the left and right both sides vicinity part 41 of 40c, it plays an auxiliary role of the upper side wall 51.

  In other words, each sliding member main body 50a acts on the lower side wall 56 so as to suppress the bending from the upper side to the lower side with respect to the left and right side vicinity portions 41 of the thick central portion 40c from the lower side.

  As a result, the bending from the upper side to the lower side with respect to the left and right both sides vicinity portion 41 of the thick central portion 40c of the left and right thin edge portions 40d as described above results in the right front sliding member 50, the left front sliding member 50, the right rear sliding. By the moving member 50 and the left rear sliding member 50, both the upper side wall 51 and the lower side wall 56 that plays an auxiliary role can be prevented even better.

  Further, as described above, the right front sliding member 50 has the upper side wall 51 and the lower side wall 56, and the right thin edge portion 40d of the shade layer 40a, the front end portions of the right side vicinity portion 41, and the skin corresponding to these both front end portions. Both the right front end portions of the layer 40b are sandwiched.

  For this reason, unlike the first embodiment, when the occupant M1 applies an upward pushing force to the sunshade 40 as an external force, the shade layer 40a first responds to the upward pushing force. Further, at the thick central portion 40c, the right front sliding member 50, the left front sliding member 50, and the right between the front and rear end portions of the left and right side guide rails 30a by the upper rail portion 31 and the lower rail portion 32, respectively. The left and right thin edge portions 40d and the thick central portion 40c sandwiched by the rear sliding member 50 and the left rear sliding member 50 are bent so as to be curved upward together with the skin layer 40b with reference to the portions 41 near both left and right sides. Mu

  However, the left and right thin edge portions 40d of the shade layer 40a and the left and right side vicinity portions 41 of the thick central portion 40c are respectively the upper and lower side walls 51 and 53 of the corresponding sliding member main body 50a at the respective front and rear end portions. It is firmly held between them.

  Therefore, when the shade layer 40a is bent upward together with the skin layer 40b at the thick central portion 40c as described above, the left and right thin edge portions 40d are shown in FIG. While being rotated, the thick central portion 40c is pulled upward together with each sliding member main body 50a as it is bent upward.

  At this time, each sliding member main body 50a abuts the inner spring portion 54a on the inner surface of the upper rail portion 31 of the left and right guide rails 30a and the outer rib portion 55b slidably contacts the inner surface of the lower rail portion 32. 12, the left and right thin edge portions 40d are rotated in the clockwise direction from the position shown in FIG. 12 in the direction of escaping from the horizontal U-shaped groove portions 34.

  However, in the second embodiment, as shown in FIG. 12, each sliding member main body 50a is adjacent to the left and right sides of the wall thickness central portion 40c of the shade layer 40a at the extended end portion thereof by the lower wall 56. The front and rear end portions of the portion 41 are uniformly in contact from the surface side.

  In addition, as described above, the shade layer 40 has the corresponding proximal end side wall portion 51a and the lower side wall 56 in the corresponding sliding member main body 50a at the front and rear end portions of the left and right thin edge portions 40d. In between, it is firmly clamped together with the skin layer 40b so that it cannot escape.

  Moreover, as described above, each sliding member 50 is formed of a resin material that is harder than the material for forming the sunshade 40, including the lower side wall 56. It is formed to a thickness that is not deformed by the external force applied to the sunshade 40 throughout.

  Therefore, as described above, each sliding member main body 50a has the left and right thin edge portions 40d on the left and right sides of the shade layer 40a while the inner spring portions 54a are kept in contact with the inner surfaces of the upper rail portions 31 of the left and right guide rails 30a. In addition, when rotating in the direction of escaping upward from each transverse U-shaped groove 34, the left and right thin edge portions 40d are adjacent to the left and right sides at the boundary portion of the right and left side portions 41 of the thick central portion 40c. It can be better maintained by the lower wall 56 so as not to fold into the region 41 from the lower side to the upper side.

  Thereby, the lower side wall 56 of each sliding member main body 50a can prevent the bending from the lower side to the upper side with respect to the left and right both sides vicinity portion 41 of the thick central portion 40c of the left and right thin edge portions 40d.

  On the other hand, each sliding member main body 50a is located on the left and right side portions 41 of the thick central portion 40c of the left and right thin edge portions 40d by the lower side wall 56 at the upper side wall 51 of the upper side wall 51 and the lower side wall 56. In the prevention of the bending from the lower side to the upper side, the lower side wall 56 plays an auxiliary role. In other words, each sliding member main body 50a acts on the upper side wall 51 so as to suppress bending from the lower side to the upper side with respect to the left and right side vicinity portions 41 of the thick central portion 40c from the upper side.

As a result, the bending from the lower side to the upper side with respect to the left and right side vicinity portion 41 of the thick central portion 40c of the left and right thin edge portions 40d as described above results in the right front sliding member 50, the left front sliding member 50, and the right rear sliding. By the moving member 50 and the left rear sliding member 50, both the lower side wall 56 and the upper side wall 51 serving as an auxiliary can be prevented even better. Other functions and effects are the same as those of the first embodiment.
