However, the operation location of the outer surface 13M of the glass plate 13 and the operation display unit 99 of the operation nameplate 44 of the operation unit 31 shown in FIG.

  Next, the structure of the door cap member 32 will be described with reference to FIG.

  The door cap member 32 shown in FIG. 5 has a lid 80, two moving means 81 and 82, two lid removal prevention means 91 and 92, and a protruding portion 93. The lid 80 of the door cap member 32 is a rectangular member formed long in the vertical direction Z in order to detachably close the opening 50 of the storage box 30. The two moving means 81, 82 and the two lid removal prevention means 91, 92 and the protruding portion 93 are provided so as to protrude from the inner surface side of the lid 80 in parallel along the insertion direction T with a gap therebetween. ing.

  The two moving means 81 and 82 are long arm-shaped members, and are respectively provided at the upper end portion and the lower end portion of the lid 80. The two lid removal prevention means 91 and 92 and the protrusion 93 are provided between the two moving means 81 and 82 so as to be symmetrical in the vertical direction perpendicular to the insertion direction. . The length of the two moving means 81 and 82 in the insertion direction T protrudes to the vicinity of the insertion tip of the operation portion 31 (shielding plate 40), and a reinforcing rib for preventing deflection is formed on the back side. . Further, the two lid removal prevention means 91 and 92 are shorter than the length of the two moving means 81 and 82 in the insertion direction T, and the protruding portion 93 has the two lid removal prevention means 91 and 92. It is shorter and wider than the length.

  The projecting portion 93 formed to project from the lid 80 swells forward in the shape of an arc, and has a U-shaped notch 93a as shown in FIG. 9, and is surrounded by the U-shaped notch 93a. The protruding piece 93b has elasticity by which the protruding piece 93b strongly pushes the peripheral portion of the operation portion 31, that is, the rear end side portion 52 of the shielding plate 40 forward by the U-shaped cutout 93a.

  By these two moving means 81, 82 and the two lid removal prevention means 91, 92 and the protrusion 93, the operation portion 31 is strongly pressed along the front P to the rear surface 13N side of the glass plate 13. To do.

  As shown in FIG. 5, the two moving means 81 and 82 preferably have elastic deformation portions 81 </ b> A and 82 </ b> A that are inclined with respect to the insertion direction T toward the insertion direction T, respectively. When the elastically deforming portions 81A and 82A of the two moving means 81 and 82 are inserted in the storage space 72 of the storage box 30 along the insertion direction T as shown in FIG. 6, the SR direction shown in FIG. 2 has a function of pressing the operation unit 31 of FIG. 2 toward the rear surface 13N side of the glass plate 13 along the front P.

  Further, the two lid removal prevention means 91 and 92 prevent the lid 80 from coming out of the opening 50 in the T1 direction when inserted in the storage space 72 of the storage box 30 along the insertion direction T. Moreover, it has a function of pressing the operation unit 31 of FIG. 2 along the front P toward the rear surface 13N of the glass plate 13.

  Next, with reference to FIG. 7 and FIG. 8, the structural example of the moving means 81 and 82 for pressing the operation part 31 with respect to the rear surface 13N of the glass plate 13 in the storage space 72 of the storage box 30 is demonstrated. .

  FIG. 7A is a cross-sectional view taken along line BB of the storage box 30, the operation unit 31, and the door cap member 32 shown in FIG. FIG. 7B is an enlarged cross-sectional view of the portion 95 shown in FIG. FIG. 7C is an enlarged cross-sectional view of the portion 96 shown in FIG. FIG. 8A is a cross-sectional view taken along line CC of the storage box 30, the operation unit 31, and the door cap member 32 shown in FIG. FIG. 8B is an enlarged cross-sectional view of the portion 97 shown in FIG. FIG. 8C is an enlarged cross-sectional view of a portion 98 shown in FIG. FIG. 9 shows a shape example of the storage box 30, the operation unit 31, and the door cap member 32.

  First, as shown in FIGS. 7A and 9, the back surface portion 100 of the storage box 30 is formed from the side surface portion 70 of the storage box 30 to the flange portion 30 </ b> P on the back side. It is inclined so that it gradually tapers along. That is, the back surface portion 100 is inclined from the opening 50 side of the storage box 30 to the flange portion 30P on the insertion tip side.

  Moreover, as shown in FIGS. 7B and 9, the back surface portion 100 further has a step portion 101 on the side of the flange portion 30P on the insertion tip side. The step portion 101 is formed so as to be narrower than the back surface portion 100 and is further inclined along the insertion direction T. The insertion portions 55, 56, and 57 shown in FIGS. 6 and 9 are fitted in the stepped portion 101 along the insertion direction T. As described above, the inclined portions 102 of the insertion portions 55, 56, and 57 fit into the stepped portion 101, so that the stepped portion 101 moves the operation unit 31 forward P with respect to the rear surface 13 </ b> N of the glass plate 13. It is designed to be pressed and stuck. That is, the step portion 101 and the insertion portions 55, 56, and 57 constitute a moving means 200 that presses the operation portion 31 against the rear surface 13 </ b> N of the glass plate 13 by moving the operation portion 31 forward P.

  Further, as shown in FIGS. 7A, 7C, and 9, the moving means 81 on the upper side of the door cap member 32 has an inclined portion 103 at its tip so that it can be easily inserted into the storage space 72. It has become. As shown in the state of FIG. 6 from the state of FIG. 5, when the moving means 81 of the door cap member 32 is inserted into the storage box 30 along the insertion direction T, as shown in FIG. The outer portion 109 of the moving means 81 is pushed forward P by the inclined back surface portion 100 and moved. Thereby, since the moving means 81 itself elastically deforms along the SR direction, the inner part 104 of the moving means 81 presses the first elastically deforming part 61 at the corresponding position along the front P. Therefore, the moving means 81 uses the first elastically deformable portion 61 to move the operating portion 31 against the rear surface 13N of the glass plate 13 by moving it forward P so as to be brought into close contact therewith. In this way, not only the moving means 81 but also the back surface portion 100 of the storage box 30 and the first elastic deformation portion 61 of the operation portion 31 move the operation portion 31 forward P with respect to the rear surface 13N of the glass plate 13. This constitutes a moving means 250 that is pressed and brought into close contact.

  Similarly, as shown in FIG. 7A, FIG. 7C, and FIG. 9, the moving means 82 on the lower side of the door cap member 32 has a tip that is easily inserted into the storage space 72. An inclined portion 103 is formed. As shown in the state of FIG. 6 from the state of FIG. 5, when the moving means 82 of the door cap member 32 is inserted in the storage box 30 along the insertion direction T, as shown in FIG. The outer portion 109 of the moving means 82 is moved by being pushed forward P by the inclined back surface portion 100. Thereby, since the moving means 82 itself elastically deforms along the SR direction, the inner part 104 of the moving means 82 presses the second elastically deformable part 62 at the corresponding position along the front P. Accordingly, the moving means 82 uses the first elastically deformable portion 62 to press the operating portion 31 against the rear surface 13N of the glass plate 13 by moving it forward P so as to be brought into close contact therewith. Thus, not only the moving means 82 but also the back surface portion 100 of the storage box 30 and the second elastic deformation portion 62 of the operation portion 31 move the operation portion 31 forward P with respect to the rear surface 13N of the glass plate 13. This constitutes a moving means 250 that is pressed and brought into close contact.

  Next, as shown in FIGS. 8A and 9, the back surface portion 100 of the storage box 30 is inclined so as to taper along the insertion direction T. That is, the back surface portion 100 is inclined from the opening 50 of the storage box 30 to the flange portion 30P on the insertion distal end side. Moreover, as shown in FIGS. 7B and 9, the back surface portion 100 has a stepped portion 101 on the side of the flange portion 30 </ b> P on the insertion tip side. The step portion 101 is inclined along the insertion direction T. An insertion portion 56 shown in FIG. 6 fits in the stepped portion 101 along the insertion direction T. At this time, since the inclined portion 102 of the insertion portion 56 is fitted into the step portion 101, the step portion 101 and the insertion portion 56 move the operation portion 31 forward P with respect to the rear surface 13N of the glass plate 13. It is designed to be pressed and stuck. In other words, the stepped portion 101 and the insertion portion 56 constitute a moving means 200 that presses the operation portion 31 against the rear surface 13N of the glass plate 13 by moving it forward P to be brought into close contact therewith.

  As illustrated in FIG. 8B, the outer portion 109 of the moving means 82 is moved forward P by the inclined back surface portion 100. Thereby, the inner part 104 of the moving means 82 (81) is pressed along the front P to the rear surface 13N side of the glass plate 13 by the plurality of circular recesses 40A of the shielding plate 40.
