PURPOSE:To use parts in common, to reduce the number of parts, and to improve producivity by making the shape of a socket base horizontally symmetric. CONSTITUTION:A V-shape mounting base 6 provided with a raised part having a pair of holes for which one end is notched, on the front part, as well as a raised part on which a pair of claws are formed, on the rear part, and a pair of box shape socket bases 7 each having a hole to be fitted to the claw, on the rear part, and a notch to be fitted and locked in a socket 3 having a claw to be inserted into the notched hole, are provided on both end parts in the longitudinal directions. When a reflecting plate 2 is attached or detached, the socket 3 slides into the notched hole for the socket of the reflecting plate 2, and rotates along with the socket base 7 and the plate is thus fitted. |
