<p>It is important to mount a mirror assembly on a shaft in such a manner as to enable tilting without a backlash. According to the present invention, an inner circumferential face of a cylinder portion 20 of a notch member 15 of a clutch mechanism 8 comes into contact with an outer circumferential face of a shaft 3, and an outer circumferential face of the cylinder portion 20 of the notch member 15 of the clutch mechanism 8 comes into contact with an inner circumferential face of a housing portion 9 of a mirror assembly 4, respectively. As a result, the present invention is capable of mounting the mirror assembly 4 on the shaft 3 in such a manner to enable tilting without a backlash, by means of the cylinder portion 20 of the notch member 15 of the clutch mechanism 8.</p> |
