Then, as shown in FIG. 5, the LED 56 is inserted and fixed from the back surface side of the holding plate 55 to the fixing hole 54 c of the fixing sheet 54 and the first insertion hole 53 c of the insertion plate 53.

    The protection plate 51 is a rectangular plate that covers the window hole 41, and is made of, for example, a transparent polycarbonate resin, and is provided on the back side of the door 4 so as to face the window hole 41.

  The map sheet 52 is a rectangular sheet and is made of, for example, a polyester resin, and is provided on the back side of the protective plate 51 so as to face the window hole 41. On the surface side of the map sheet 52, for example, by virtue of direct printing, a warning monitoring area is graphically displayed by a map 52a or the like as shown in FIG. The translucent part 52b is arrange | positioned at 52a.

  The insertion plate 53 is a rectangular plate and is made of, for example, an opaque ABS resin, and is provided on the back side of the map sheet 52. A large number of cylindrical first insertion holes 53c as light passages are formed in a matrix in the insertion plate 53, and are formed in 18 rows and 24 columns in the drawing. The inner diameter of the first insertion hole 53 c is substantially the same as the outer diameter of the head portion 56 a of the LED 56. Further, the insertion plate 53 is provided with a notch 53b having the same shape as that of the fixed sheet 54 on the inner side and on the back side.

  The fixed sheet 54 is a rectangular sheet and is made of, for example, silicone rubber as an elastic body, and is disposed on the back side of the insertion plate 53, specifically, in the notch 53 b of the insertion plate 53. It has become. Therefore, it is easy to align the many insertion holes 53c of the insertion plate 53 and the corresponding many fixing holes 54c of the fixing sheet 54 corresponding thereto. The fixing sheet 54 has a large number of cylindrical fixing holes 54c for fixing the LEDs 56 formed in a matrix corresponding to the large number of first insertion holes 53c. The inner diameter of the fixing hole 54 c is narrower than the outer diameter of the head 56 a of the LED 56.

  The presser plate 55 is a substantially rectangular plate made of, for example, steel, and is provided on the back side of the fixed sheet 54. In addition, the holding plate 55 is formed with a plurality of cylindrical second insertion holes 55c for insertion of the LEDs 56 in a matrix corresponding to the plurality of first insertion holes 53c. The inner diameter of the second insertion hole 55 c is larger than the outer diameter of the flange portion 56 b of the LED 56.

  The LED 56 includes a bullet-shaped head 56a, a flange 56b having a diameter larger than the outer diameter of the head 56a, and a lead wire 56c. The LED 56 inserts the head portion 56a into the second insertion hole 55c from the back surface side of the presser plate 55, so that the translucent portion 52b of the map sheet 52 is made to pass through the fixing hole 54c and the first insertion hole 53c. Can be irradiated. And it fixes in the fixing hole 54c, and is hold | maintained in the 1st penetration hole 53c.

    In other words, using the cross-sectional view of FIG. 5, the head portion 56 a of the LED 56 is first inserted into the second insertion hole 55 c of the holding plate 55 and then inserted into the fixing hole 54 c of the fixing sheet 54. . At this time, the inner diameter of the fixing hole 54c is smaller than the outer diameter of the head portion 56a, but since it is an elastic body, the diameter is increased by inserting the head portion 56b to allow the insertion of the head portion 56b. 56 is inserted into the first insertion hole 53 c of the insertion plate 53. When the flange portion 56b of the LED 56 comes into contact with the back surface side of the fixing sheet 54, the fixing hole 54c has a diameter that does not allow the insertion of the flange portion 56b, so that each LED 56 is attached at a predetermined position in the insertion direction. It is done. As another method, even if the fixing hole 54c has a diameter allowing the insertion of the flange portion 56b, it is confirmed that the flange portion 56b of the LED 56 is in contact with the back side of the fixed sheet 54, and the LED 56 is inserted. By stopping the operation, the individual LEDs 56 can be defined and attached at predetermined positions with respect to the insertion direction.

In addition, since the inner diameter of the first insertion hole 53c is formed to be substantially equal to the outer diameter of the head 56a of the LED 56, the head 56a is held appropriately in the first insertion hole 53c so as not to be damaged. can do. That is, the head 56b of the LED 56 can be more reliably fixed by the cooperation of the fixing hole 54c and the first insertion hole 53c. Even if the inner diameter of the first insertion hole 53c is larger than the outer diameter of the head portion 56a of the LED 56, there is no problem with fixing.

  Through the first insertion hole 53c, the light from the LED 56 illuminates the map sheet 52 through the first insertion hole 53c when necessary, and turns on the translucent portion 52b of the drawn map 52a. At this time, the first insertion hole 53c also serves as a light guide. Since the inner diameter of the first insertion hole 53c is formed to be substantially equal to the outer diameter of the head portion 56a of the LED 56, it is possible to prevent variation in the irradiation axis of the LED 56 and make it constant.

    The inner diameter of the second insertion hole 55c of the holding plate 55 is larger than the outer diameter of the head portion 56a of the LED 56 and smaller than the outer diameter of the flange portion 56b of the LED 56, so that the Even if the portion 56b is in contact with the back side of the presser plate 55, the individual LEDs 56 can be specified and attached at predetermined positions in the insertion direction.

    Incidentally, as described above, the map sheet 52, the insertion plate 53, the fixing sheet 54, and the presser plate 55 are unitized. Since the single sheet-like fixing sheet 54 is used as a fixing member for fixing the LED 56, the alignment of the many insertion holes 53c of the insertion plate 53 and the many fixing holes 54c of the fixing sheet 54 is individually performed. Compared to the case of alignment, it is easy and the assemblability is good. Further, since the fixing sheet 54 is held on the back surface side of the insertion plate 53 by the holding plate 55, the holding of the large number of insertion holes 53c of the insertion plate 53 and the large number of fixing holes 54c of the fixing sheet 54 is individually held. Compared with, it is easy to assemble.

    Here, as the presser plate 55, a single plate-like presser plate 55 in which a number of second insertion holes 55c are formed corresponding to the number of first insertion holes 53c of the insertion plate 53 is used. And the fixing sheet 54 come into contact with each other in a planar shape, and the fixing hole 54c of the fixing sheet 54 can be prevented from floating from the insertion hole 53c of the insertion plate 53, so that each LED 56 has a predetermined position in the insertion direction.
