It is formed by laminating, for example, five sheets of two types of transparent plate materials 11A and 11B that have the function of transmitting light. The plate materials 11A and 11B are made of, for example, acrylic plates. As shown in FIG. 3, the plate material 11A has a reflective surface 12 therein, and an optical path L1 is bent so as to go around the spoke 1c. The light entering from the light inlet 11A-1 is bent several times to the right or left at approximately 90 degrees by the reflective surface 12, and is directed toward the light outlet 11A-2 and exits from the light outlet 11A-2 to the outside. . On the other hand, the plate material 11B does not have the above-mentioned reflective surface as shown in FIG.
L 2 is formed linearly in the vertical direction. Therefore, the upper surface portion 11B-1 of the plate material 11B forms the light incident surface,

Or when the plate material 11A is in the position Q, the reflective surface 1
2 reflects the light outward, making it impossible to form an optical path. Also, when each end surface is in the R position, the plate material 11B has a spoke 1 in the center.
Since c exists, it is not possible to form an optical path.
As described above, as the spokes 1c move due to the rotation of the steering wheel, the plates 11A and 11B complement each other to form an optical path. Thus, the light guide section 11 having the structure as described above
are attached to the spokes 1c of the steering wheel 1, so that an optical path can be secured between the light guide paths 9, 10 and the light guide 5 without being blocked by the spokes 1c.
