PROBLEM TO BE SOLVED: To effectively suppress the displacement of a mirror adjusting member at the time of screw fixation by providing a specific turning force transmission restriction member for the mirror adjusting mechanism which is so constituted as to fix the mirror adjusting member to a mirror support member with a screw. SOLUTION: The mirror adjusting mechanism 10 is so constituted that a mirror adjusting bracket 18 is fixed to a housing 12 with a screw after a mirror 116 is adjusted to a specific angle by moving the mirror adjusting bracket 18 against the elastic pressing force of an upper leaf spring 16, and an oval type washer 20 fitted in the upper projection part 12c of the housing so that it can not rotate is interposed between the mirror adjusting bracket 18 and the screw 26 for fixing it. Consequently, the mirror adjusting mechanism 10 can be made simple and small-sized and the turning force operating on the screw 26 is prevented from being transmitted as a rotary frictional force to the mirror adjusting bracket 18 to prevent the mirror adjusting bracket 18 from being displaced at the time of screw fixation. |
