【Example】

  Next, the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment of the present invention. FIG. 2 is a perspective view, and FIG. 2 is an enlarged sectional view taken along the line AA. In these figures, 1 Is a base plate made of a horizontally long aluminum plate, and 2 is approximately the same size as the base plate 1. Is a retroreflective sheet formed by the It is adhered to the surface of the base plate 1. This retroreflective sheet 2 is a base film. The glass beads 5 are arranged on the surface of the rum 4, and the partition wall 4 is integrated with the base film 4. After forming a, the over film 7 is supported so as to cover the entire surface, and an air layer is formed inside. Is defined. Then, the retroreflective sheet 2 is sized as the size of the base plate 1. And cut it to a base plate 1 and form a required pattern on the surface. The fluorescent film 8 is attached.

[0009]   In addition, a plurality of circular mounting holes 9 are formed at required positions in the reflecting plate, These mounting holes 9 penetrate the retroreflective sheet 2 and the base plate 1 in the thickness direction. It Then, the bolt 10 is inserted through the mounting hole 9, and the bolt 10 is attached to the vehicle. The reflector is fixed to the vehicle body 11 with the bolts 10 by screwing it onto the vehicle body 11 of I am making it. An annular washer 12 is inserted between the bolt 10 and the reflector. is doing. As shown in the enlarged view of FIG. 3, the washer 12 has a central portion that is Compared to this, it is configured to be thicker, and due to this difference in thickness, a stepped portion is formed on the inner surface of the washer periphery. 12a is provided.

[0010]   Therefore, according to this configuration, even if the bolt 10 is fastened, the head of the bolt 10 Since the washer 12 is interposed between and the reflection sheet 2, the bolt head and the reflection sheet Since there is no direct contact between the two, the shearing force due to the frictional force does not occur between the two The seat 2 can be prevented from being damaged. In addition, by tightening the bolts 10 around the mounting hole 9 The wrinkles 7a of the over film 7 may be generated. Since the wrinkles 7a are generated in the vicinity of the stepped portion 12a provided in the peripheral portion of the washer 1, It can be covered by the peripheral part of 2, and the deterioration of the appearance can be prevented.

[0011]   Here, when the reflection sheet 2 is cut to a required size, the inner periphery is cut off. There is a problem that the air layer is exposed and moisture and dust enter the inside to lower the reflectance. Although there is a possibility that it will occur, the reflection sheet 2 should be placed around the reflection plate as shown in Fig. 4. And squeeze it with the hot press method to bring the over film 7 into close contact with the base film 4. If it is fluffy, the air layer is not exposed at the peripheral portion of the reflection sheet 2, and the reflection sheet is not exposed. It is possible to prevent the reflectance of the grate 2 from decreasing.   In addition, the mounting holes on the reflector plate are the mounting holes 9A only on the base plate as shown in FIG. Keep the bolts at the mounting holes of the base plate 1 when actually mounting the reflector. By strongly pressing against the reflection sheet 2, a mounting hole is formed in the reflection sheet 2. You may do it. By doing this, it is possible to prevent unnecessary mounting holes from occurring, Prevents deterioration of the appearance due to unused mounting holes, and prevents reflections in the mounting holes. The air layer inside the camera is exposed, and moisture and dust penetrate inside, causing a decrease in reflectance. Can be prevented in advance.

[0012]   FIG. 6 is a sectional view of an essential part of the second embodiment of the present invention. Here, the mounting hole 9 is provided A circular patch sheet 13 made of thick film urethane is attached to the surface of the reflective sheet 2. Attached. For this reason, when the bolt is inserted into the mounting hole 9 to fix the reflection plate, Even if they are in contact, the patch sheet 13 prevents direct contact between the head of the bolt and the reflective sheet. Therefore, the reflection sheet 2 can be prevented from being damaged due to shearing. Also, on the patch sheet 13 Therefore, it goes without saying that wrinkles do not occur in the over film 7 around the mounting holes.   In this embodiment, an annular patch sheet is used, but a circular patch sheet is used. Affix to the upper part of the mounting hole and use a screw such as a wood screw to make a hole in the patch sheet. You may fix it, opening.
