The third protruding portion 74 extends from the side wall portion 56 to the other end of the base portion 44 above the second protruding portion 72. The fourth projecting portion (connecting rib, pedestal side rib) 76 extends above the third projecting portion 74 from above the side wall portion 56 to the second wall portion 54b constituting the connecting wall portion 54 described later. ing.

  The protruding length of each of the first to fourth protruding portions 70 to 76 gradually increases from one end to the other end. That is, the front end surface of each of the first to fourth projecting portions 70 to 76 is inclined toward the base portion 44 side by a predetermined angle θ with respect to the plane of the base portion 44 toward the side wall portion 56 side. Thereby, each front end surface of the 1st-3rd protrusion parts 70-74 contacts the front surface (surface which faces the base part 44) of the connector part 206, and the front end surface of the 4th protrusion part 76 is the illumination part 208. It will come into contact with the front.

  The movement restricting portion 52 is substantially H-shaped along the extending direction of the side wall portion 56 from a portion of the back surface (back surface) of the base trim 14 located above the end portion 38 of the light guide 34 (Z2 direction). Protrusions are formed. The movement restricting portion 52 includes a pair of restricting plates 82 and 84 that are provided on the back surface of the base trim 14 and face each other, and an intermediate plate 86 that connects the restricting plates 82 and 84.

  Each of the regulating plates 82 and 84 is gradually narrowed toward the tip. The lower end portion of the restriction plate 82 is cut off at the front end side of the restriction plate 82, so that the upper restriction surface 82 a that contacts the upper surface side of the flange 230 formed in the illumination portion 208 and the front surface side of the flange 230 (including the illumination portion). A front restricting surface 82b that is in contact with the front face 208). Similarly, the lower portion of the restriction plate 84 is cut off at the front end side of the restriction plate 84, so that the upper restriction surface 84 a that contacts the upper surface side of the flange 230 and the front restriction surface 84 b that contacts the front surface side of the flange 230. And are formed.

  The connection wall portion 54 is a cylindrical portion formed so as to surround the end portion 38 and the connection portion 204 of the light guide 34. That is, the connecting wall portion 54 connects the upper side wall portion 48 and the one restricting plate 82, and the curved first wall portion 54a that covers the outer peripheral surface of the end portion 38 and the connecting portion 204 from the left side, The fourth protruding portion 76 and the other restricting plate 84 are connected to each other, and the second wall portion 54b having a curved shape that covers the outer peripheral surface of the end portion 38 and the connecting portion 204 from the right side is formed. Accordingly, the first wall portion 54a and the second wall portion 54b are provided to face each other with the end portion 38 of the light guide 34 and the connection portion 204 interposed therebetween.

  In this case, the first wall portion 54a is formed with a first relief portion (first wall portion side relief portion) 88a that is curved so as to be radially separated from the outer peripheral surfaces of the end portion 38 and the connection portion 204. . On the other hand, the second wall portion 54b is formed with a second relief portion (second wall portion side relief portion) 88b that is curved so as to be radially separated from the outer peripheral surface of the end portion 38 and the connection portion 204. The first relief portion 88a and the second relief portion 88b are formed so as to face each other with the end portion 38 and the connection portion 204 interposed therebetween (see FIGS. 3 to 6 and 8). The second escape portion 88b is formed at a position lower than the first escape portion 88a. Further, the second escape portion 88b is spaced radially from the outer peripheral surface of the end portion 38 and the connection portion 204 (the separation amount is larger than that of the first escape portion 88a), compared to the first escape portion 88a.

  Thereby, the space (gap) formed between the outer peripheral surface of the end portion 38 of the light guide 34 and the connection portion 204 and the second escape portion 88b is between the outer peripheral surface and the first escape portion 88a. It becomes larger than the formed space. As a result, when the lighting device 200 is mounted on the mounting structure 10, for example, the operator touches the side surface (right side surface) of the claw portion 216 of the lighting unit 208 with the thumb and the side surface (left side) of the claw portion 214. The connecting portion 204 can be easily put in and out of the cylindrical connecting wall portion 54 while the illumination portion 208 is gripped by touching the surface) with the index finger.

  Further, a hole (pedestal side escape portion) 90 is formed in the upper side wall portion 48. Thereby, when the connection part 204 is inserted inside the connection wall part 54, interference with the connection part 204 and the upper side wall part 48 can be avoided. In the present embodiment, it is only necessary to avoid interference between the connecting portion 204 and the upper side wall portion 48. Therefore, the escape portion with respect to the connecting portion 204 may be a concave portion recessed vertically downward instead of the hole 90. .

  Further, the curved surface 36 is provided with a first rib (first wall portion side rib) 92a connected to the outer peripheral surface of the first wall portion 54a and connected to the outer peripheral surface of the second wall portion 54b. A second rib (second wall portion side rib) 92b is erected. The first rib 92a is formed integrally with the curved surface 36, and connects the curved surface 36 with the location of the first relief portion 88a in the first wall portion 54a. The second rib 92b is formed integrally with the curved surface 36, and connects the curved surface 36 with the location of the second relief portion 88b in the second wall portion 54b.

  The fourth protrusion 76 described above is connected to the second wall 54b so as to be continuous with the second wall 54b, and the movement restricting portion 52 includes the first wall 54a and the second wall 54b. It is connected. Thereby, the end part 38 and the connection part 204 of the light guide 34 are cylindrical ribs constituted by the movement restricting part 52, the connecting wall part 54, the fourth projecting part 76, the first rib 92a and the second rib 92b. It becomes a state surrounded by.

  The mounting structure 10 is schematically configured as described above. Next, the configurations of the light guide 34 and the switch unit 26 that are coupled to the connection unit 204 of the lighting device 200 fixed by the mounting structure 10 will be described with reference to FIGS. 1 to 6 and FIGS. 8 to 12. explain.

  An insertion hole 100 is formed in the base trim 14 so as to face the connection portion 204 of the lighting device 200 fixed to the mounting structure 10. Moreover, as shown in FIG.1 and FIG.10, the light guide 34 is a substantially J-shaped light guide member. Therefore, as described above, the light guide 34 is fixed to the inner hole 232 of the connecting portion 204 by the protrusion 39 engaging the engaging portion 233, and through the insertion hole 100, the end portion 38 is fixed. It extends to the switch part 26.

  Specifically, as shown in FIG. 10, an accommodation groove 102 for accommodating the light guide 34 is formed along the shape of the door armrest 22 and the switch portion 26 at the edge on the upper end side of the door armrest 22. . That is, the housing groove 102 extends inward in the vehicle width direction (Y2 direction) from the insertion hole 100, curves toward the rear of the vehicle at the front corner of the door armrest 22, and extends rearward along the inner side of the switch portion 26 in the vehicle width direction. It extends to. Therefore, the portion of the light guide 34 on the inner side in the vehicle width direction (the portion in the Y2 direction than the insertion hole 100) extends along the accommodation groove 102 formed along the edge on the upper end side of the door armrest 22, Be contained.

  FIG. 10 illustrates a state where the switch panel 30 is removed from the door armrest 22. Therefore, as shown in FIG. 1, when the upper side of the door armrest 22 is covered with the switch panel 30, the vehicle occupant cannot directly view the light guide 34.

  Around the insertion hole 100, when the light incident on the end portion 38 of the light guide 34 from the light emitting element 201 of the lighting device 200 is guided to the inner side in the vehicle width direction of the light guide 34, the light enters the door. A wall portion for preventing leakage from the gap between the armrest 22 and the switch panel 30 is provided.

  Specifically, a rib (light leakage prevention wall) 104 is erected from the door armrest 22 and the base trim 14 so as to surround the insertion hole 100. In this case, the portion of the rib 104 on the door armrest 22 side is erected from the door armrest 22 so as to cover the front side of the light guide 34 and the base trim 14 side of the light guide 34 from above. It is erected from the base trim 14 so as to cover it.

  As described above, since the switch panel 30 covers the upper side of the door armrest 22, light from the light guide 34 leaks to the outside through the gap between the door armrest 22 and the switch panel 30 at the front of the vehicle by providing the rib 104. This can be suppressed.

  As shown in FIGS. 11A to 12, in a cross-sectional view, a concave portion 106 is formed on the upper side of a portion of the light guide 34 that extends in the vehicle front-rear direction, and a notch 108 is formed on the bottom. ing. Therefore, in order to accommodate the light guide 34, an engagement claw 110 and a contact rib 111 that engage with the recess 106 are formed in the accommodation groove 102, and a support rib 112 that supports the notch 108 is formed. ing. In addition, a nonwoven fabric 114 is inserted in the gap between the light guide 34 and the housing groove 102 around the supporting rib 112.

  Specifically, in the cross-sectional views of FIGS. 11A to 12B, the housing groove 102 is opened in the vehicle width direction inner side (Y2 direction), while the vehicle width direction outer side (Y1 direction) is formed as the bottom surface 115. . In this case, the engaging claw 110 is engaged with the recess 106 on the outer side in the vehicle width direction. The abutment rib 111 is provided on the upper side of the housing groove 102 and abuts on the upper portion of the light guide 34.

  Further, the notch 108 is formed on the bottom 115 side of the receiving groove 102 at the bottom of the light guide 34. The support rib 112 is provided in an L-shaped cross section from the bottom surface 115 of the receiving groove 102 to the cutout portion 108. The nonwoven fabric 114 is inserted in a gap between the upper portion of the light guide 34 and the upper side of the housing groove 102, or a gap between the bottom surface 115 side of the light guide 34 and the bottom surface 115 side of the support rib 112.

  As shown in FIG. 10, it is preferable that a plurality of the engaging claws 110, the contact ribs 111, the supporting ribs 112, and the nonwoven fabrics 114 are provided at predetermined intervals along the housing groove 102. Thereby, the light guide 34 can be positioned and accommodated in the accommodation groove 102.

  11A and 11B, when the switch panel 30 is covered from above the door armrest 22, a gap 116 between the door armrest 22 and the switch panel 30 is formed on the inner side in the vehicle width direction than the light guide 34. It is formed. Thereby, when light is introduced from the light emitting element 201 of the lighting device 200 to the light guide 34, the light from the light guide 34 is output to the inside in the vehicle width direction through the gap 116. As a result, the vehicle occupant can visually recognize the output light.

  A procedure for attaching the lighting device 200 to the curved surface 36 and a procedure for attaching the light guide 34 to the connecting portion 204 of the lighting device 200 after the mounting using the mounting structure 10 configured as described above will be described.

  When attaching the lighting device 200 to the curved surface 36, first, the front surface of the connector portion 206 is opposed to the base portion 44, and the connecting portion 204 is aligned with the position of the connecting wall portion 54.

  In this case, since the step portion 220 is formed on the side surface 218 of the connector portion 206 and the side surface 222 is formed in a flat shape, the worker can connect the side surface 218 and the step portion 220 side of the lighting device 200 to the side wall portion. 56, and the side surface 222 side of the lighting device 200 is opposed to the engaging claw 58. Further, when the operator faces the front surface of the lighting device 200 toward the mounting structure 10, the worker aligns the lighting device 200 so that the slit 236 is on the right side with the slit 236 of the connection portion 204 as a mark. .

  Thereby, while being able to perform position alignment of the illuminating device 200 with respect to the attachment structure 10 reliably, the incorrect assembly | attachment of the illuminating device 200 with respect to the attachment structure 10 can be prevented. When the lighting device 200 is advanced toward the base 40 in this state, the front surface of the connector portion 206 contacts the tapered surface 68 of the engaging claw 58.

  Subsequently, when the lighting device 200 is pressed toward the base portion 44, the support wall portion 60 is elastically deformed so that the engaging claw 58 is displaced in a direction away from the side wall portion 56, and the side wall portion 56 and the engaging claw 58 are thus deformed. The connector part 206 enters between the two. When the lighting device 200 is further pushed toward the base portion 44, the engaging claw 58 that has passed over the connector portion 206 returns to the original position and contacts the back surface of the connector portion 206.

  At this time, the front surface of the connector portion 206 is in contact with the tip surfaces of the first to third projecting portions 70 to 74. That is, the connector portion 206 is fixed to the base portion 44 because the rear surface thereof contacts the engaging claw 58 in a state where the front surface thereof is in contact with the tip surfaces of the first to third projecting portions 70 to 74. Will be.

  Further, in the above-described installation of the lighting device 200, the operator touches the right side surface of the nail portion 216 of the illumination unit 208 with the thumb, touches the left side surface of the nail unit 214 with the index finger, and holds the illumination unit 208 in a state where The connecting portion 204 is inserted inside the connecting wall portion 54. In this case, since the second relief portion 88 b is greatly separated from the outer peripheral surface of the connection portion 204, it is easy to insert the connection portion 204 into the tubular connecting wall portion 54. Moreover, since the hole 90 is formed in the upper side wall portion 48, the connection portion 204 can be inserted inside the connecting wall portion 54 while avoiding interference between the connection portion 204 and the upper side wall portion 48.

  Further, by attaching the lighting device 200 to the attachment structure 10, one side surface 218 of the connector portion 206 is in surface contact with the side wall portion 56, and the other side surface 222 of the connector portion 206 is in line contact with the convex portion 64 and the wall portion. 78 is contacted. As a result, rattling of the connector part 206 with respect to the base part 44 is suppressed.

  Furthermore, the front surface of the illumination unit 208 comes into contact with the distal end surface of the fourth protrusion 76 and the other side surface of the illumination unit 208 comes into contact with the second wall 54b. Thereby, the backlash of the illumination part 208 with respect to the base part 44 is suppressed.

  Furthermore, one flange portion 210 of the connector portion 206 contacts the wall surface of the side wall portion 56, and the other flange portion 212 contacts the engaging claw 58. Therefore, the movement of the lighting device 200 in the vertically downward direction (Z1 direction) with respect to the base portion 44 is restricted. That is, the side wall part 56 and the engaging claw 58 function as a movement restricting unit that restricts the downward movement of the lighting device 200. However, the flange portion 210 may be non-contact with the side wall portion 56 and the flange portion 212 may be non-contact with the engaging claw 58 in a state where the lighting device 200 is mounted on the mounting structure 10. Good. Even in this case, it is possible to restrict the downward movement of the lighting device 200.

  Further, since the flange 230 of the illumination unit 208 comes into contact with the upper restriction surfaces 82a and 84a, the movement along the vertical upper direction (Z2 direction) of the illumination device 200 fixed to the base unit 44 is restricted. Thereby, when the lighting device 200 moves vertically upward with respect to the base portion 44 in a state where the end portion 38 of the light guide 34 is fixed to the connection portion 204, an excessive force acts on the light guide 34. Can be prevented.

  However, the upper restriction surfaces 82a and 84a may be non-contact with the upper surface of the illumination unit 208 in a state where the illumination device 200 is mounted on the attachment structure 10. Even in this case, it is possible to suppress the amount of vertical upward movement of the lighting device 200 with respect to the base portion 44, and thus it is possible to prevent an excessive force from acting on the light guide 34.

  Furthermore, since the front surface including the flange 230 of the illumination unit 208 is in contact with each of the front regulation surfaces 82b and 84b, the forward movement of the illumination unit 208 is regulated. Therefore, it is possible to prevent the illumination unit 208 from moving forward with respect to the base unit 44 and applying an excessive force to the light guide 34 connected to the connection unit 204.

  However, the front regulating surfaces 82b and 84b may be non-contact with the front surface of the illumination unit 208 in a state where the illumination device 200 is mounted on the mounting structure 10. Even in this case, since the amount of forward movement of the lighting device 200 with respect to the base portion 44 can be reduced, it is possible to prevent an excessive force from acting on the light guide 34.

  Furthermore, the connecting portion 204 is positioned vertically above the upper wall portion 48 (Z2 direction), and the claw portion 216 provided on the illumination portion 208 is positioned vertically above the second wall portion 54b and the fourth projecting portion 76. To do. Thereby, even when the lighting device 200 moves along the vertically downward direction (Z1 direction) with respect to the base portion 44, the connection portion 204 contacts the upper wall portion 48 and the claw portion 216 has the second wall portion 54b. And since it contacts the 4th protrusion part 76, the movement to the vertically downward direction of the illuminating device 200 is controlled. That is, the upper wall portion 48, the second wall portion 54b, and the fourth projecting portion 76 function as a movement restricting unit that restricts the movement of the lighting device 200 in the vertically downward direction.

  After the lighting device 200 is fixed to the mounting structure 10 in this manner, the end portion 38 of the light guide 34 is inserted into the connection portion 204 of the lighting device 200 and the light guide 34 is received in the receiving groove 102. To do.

  In this case, the end portion 38 of the light guide 34 is inserted from the inner side in the vehicle width direction of the door lining 12 toward the insertion hole 100. The end portion 38 that has passed through the insertion hole 100 faces the connection portion 204. Next, the end portion 38 is positioned so that the protrusions 39 are positioned vertically. In this state, the end portion 38 is advanced toward the connection portion 204.

  Thereby, in a state where the tip portion of the end portion 38 is inserted into the inner hole 232 of the connection portion 204, each projection portion 39 on the end portion 38 side contacts the engagement portion 233 formed inside the connection portion 204. To do. Each engaging portion 233 is in a cantilever state with the base end side of the connecting portion 204 as a fulcrum. Therefore, when the end portion 38 is further advanced, the engaging portion 233 is displaced in a direction away from the end portion 38 and the cantilever portion of the connection portion 204 is elastically deformed.

  Then, when the end portion 38 is further pushed forward and each projection 39 passes the position of the engagement portion 233, each engagement portion 233 returns to the original position and contacts the rear of each projection 39. As a result, the end portion 38 of the light guide 34 is fixed to the mounting structure 10 via the lighting device 200 in a state of being inserted into the inner hole 232 of the connection portion 204.

  On the other hand, a portion on the inner side in the vehicle width direction from the insertion hole 100 in the light guide 34 is accommodated in an accommodation groove 102 formed along the door armrest 22. In this case, the engaging claw 110, the abutment rib 111, the supporting rib 112, and the nonwoven fabric 114 are provided at predetermined intervals in a portion along the vehicle longitudinal direction in the accommodation groove 102. Therefore, the concave portion 106 of the light guide 34 engages with the engaging claw 110, the upper portion of the light guide 34 abuts against the contact rib 111, and the notch 108 is supported by the support rib 112. In addition, the nonwoven fabric 114 is inserted in the gap between the light guide 34 around the supporting rib 112 and the receiving groove 102 and the supporting rib 112. Thereby, the light guide 34 can be reliably accommodated in the accommodation groove 102.

  After the light guide 34 is accommodated in the accommodation groove 102 in this way, the switch panel 30 is covered from above the door armrest 22. Thereby, when the light emitting element 201 of the illumination device 200 emits light and the emitted light enters the end portion 38 of the light guide 34, the light incident on the light guide 34 passes through the insertion hole 100. , Led to the switch unit 26. In this case, since the rib 104 is formed so as to surround the insertion hole 100, a part of the light guided to the light guide 34 around the insertion hole 100 (the vehicle front side) is the door armrest 22 and the switch panel. Leakage from the gap with 30 can be suppressed.

  On the other hand, a gap 116 is formed in the vehicle front-rear direction along the switch portion 26 in the gap between the door armrest 22 and the switch panel 30. Thereby, the light guided by the light guide 34 is output to the vehicle interior side through the gap 116, and the vehicle occupant can visually recognize the output light.

  As described above, in the mounting structure 10 of the lighting device 200 according to the present embodiment, the stepped portion 32 is formed on the door lining 12 to be mounted by the door armrest 22, the switch portion 26, and the recessed portion 24, and is attached to the stepped portion 32. By providing the structure 10, the lighting device 200 is installed on the stepped portion 32 using the mounting portion 42 that constitutes the mounting structure 10.

  That is, by providing the door lining 12 with the door armrest 22, the switch part 26, and the recessed part 24, the said part turns into a protrusion part (expansion part), and the level | step-difference part 32 is formed. By effectively utilizing such a stepped portion 32 as the installation location of the illumination device 200, the installation location of the illumination device 200 with respect to the door lining 12 can be easily ensured.

  Moreover, since the illuminating device 200 is installed in the level | step-difference part 32 using the attaching part 42, the illuminating device 200 can be stably attached to the level | step-difference part 32 without using a screw member, and an attachment man-hour can be reduced.

  Moreover, if the end portion 38 of the light guide 34 installed in the door lining 12 is inserted into the illumination device 200 installed in the stepped portion 32, the light emitted from the illumination device 200 is incident on the end portion 38, The light guide 34 can be guided.

  In this embodiment, the hole 90 serving as the escape portion that avoids the connection portion 204 is provided in the upper wall portion 48 of the base 40, so that the lighting device 200 is fixed to the base portion 44 and connected to the upper wall portion 48. Interference with the unit 204 can be avoided. Thereby, the assembly | attachment property of the illuminating device 200 with respect to the door lining 12 can be improved. In addition, as a relief part provided in the base 40 side in this way, a recessed part may be sufficient other than the hole 90, for example.

  In the present embodiment, the connecting portion 204 and the end portion 38 of the light guide 34 are surrounded by the cylindrical connecting wall portion 54 protruding from the step portion 32, so that the light guide 34 is connected to the lighting device 200. When light enters the end portion 38, the light can be prevented from leaking to the outside.

  Furthermore, in this embodiment, the 1st escape part 88a and the 2nd escape part 88b are formed in the 1st wall part 54a and the 2nd wall part 54b which comprise the connection wall part 54, respectively. In this case, the second escape portion 88b is formed so as to be more radially separated from the outer peripheral surface of the connection portion 204 and the end portion 38 of the light guide 34 than the first escape portion 88a.

  Thereby, when fixing the illuminating device 200 to the base portion 44, the operator connects the connecting portion 204 to the connecting wall portion 54 in a state where the illuminating portion 208 (the connecting portion 204 side of the illuminating device 200) is sandwiched between the thumb and the index finger. Insert it inward. At this time, the thumb can easily enter the space between the second relief portion 88 b and the connection portion 204, and the index finger can easily enter the space between the first relief portion 88 a and the connection portion 204. As a result, the lighting device 200 can be easily assembled to the step portion 32.

  When the base portion 44 is formed in the vertical direction and the connection portion 204 is inserted into the connecting wall portion 54 with the connection portion 204 facing upward, the first relief portion 88a is provided at a high position, If the two escape portions 88b are provided at a low position and a height difference is made between the first escape portion 88a and the second escape portion 88b, the assembling property of the lighting device 200 can be further improved.

  Further, in the present embodiment, the pedestal 40 and the connecting portion 54 and the stepped portion 32 or the pedestal 40 are connected by various ribs (fourth projecting portion 76, first rib 92a, second rib 92b). The rigidity of the wall part 54 can be improved.

  Specifically, the rigidity of the pedestal 40 and the second wall portion 54b can be improved by connecting the second wall portion 54b and the base portion 44 constituting the pedestal 40 with the fourth projecting portion 76. In particular, since the fourth projecting portion 76 is formed in the vicinity of the hole 90, the fourth projecting portion 76 can reinforce the decrease in rigidity of the base 40 due to the formation of the hole 90.

  Further, the first wall portion 54a and the curved surface 36 constituting the stepped portion 32 are connected by the first rib 92a, and the second wall portion 54b and the curved surface 36 are connected by the second rib 92b, thereby The rigidity of the 1st wall part 54a, the 2nd wall part 54b, and the base 40 can be improved further.

  Further, in the present embodiment, the movement restricting unit 52 restricts the movement of the lighting device 200 upward and the movement of the lighting device 200 in the direction away from the base unit 44, thereby shifting the position of the lighting device 200 with respect to the base unit 44. Can be suppressed.

  Furthermore, in the present embodiment, with the lighting device 200 fixed to the base portion 44, the end portion 38 of the light guide 34 is inserted into the inner hole 232 of the connecting portion 204, and each protrusion 39 and each engagement portion are inserted. By engaging the joint portion 233, the lighting device 200 and the light guide 34 can be reliably fixed to the base portion 44.

  Moreover, in this embodiment, in order to fix the illuminating device 200 previously, the insertion position of the edge part 38 of the light guide 34 with respect to the connection part 204 is decided previously.
