Abstract

PURPOSE:To perform transmission of light in an easy and efficient manner in a unit which performs the light transmission between a photo signal generating means and a photo signal processing means which are disposed on the upper and the lower side of a steering wheel by providing a light guide passage at a part of said wheel where a light transmission path is cut off. CONSTITUTION:A pad 2 is disposed at the upper and middle site of the upper part of a steering wheel 1 and a light transmission and receival processing part 3 is disposed at the lower site thereof which is on the side of a car body. A photo switch device 4 which is a photo signal generating means and a light guide passage 5 which transmits light thereto are included in said pad 2. On the other hand, a luminescent element 7 and a light receiving element 8 are included in the processing part 3 and face to light guide passages 9 and 10 which opposed to the light-in end 5a and a light-out end 5b of the light guide passage 5, respectively. Light guide passage 11 are formed in the wheel 1 at the positions where a spoke 1c thereof meets the lights paths. The spoke 1c may therefore be prevented from cutting off the light paths and the desired purpose be attained.

When the end face is at the position (R), an optical path is formed by the plate material (IIA). When the end faces of the light guide paths (5) and (10) are at the position (P) or (Q), the plate material (IIA)
Since the light is reflected outward by the reflective surface (12), it is not possible to form an optical path. Also, each end face is (R)
When the plate material (IIB) is in the position shown in FIG. Therefore, as mentioned above, as the spokes (lc) move due to the rotation of the steering wheel, the plate material (IIA
