PURPOSE:To make the readjustment of a mirror angle needless by so supporting the inner end of a lever for mirror angle adjustment as to be free in leftward and rightward movement or rotation to a base longitudinal wall and connecting a shaft to a longitudinal lever capable of rotation to the longitudinal wall and connecting a transverse lever mounted on the shaft with a mirror holder. CONSTITUTION:When a transverse lever 25 is rotated by working a lever 9, a mirror holder rotates in the leftward/rightward direction so as to adjust the leftward/rightward deflection angle of a mirror 8. On the other hand, when the transverse lever 25 is elevated, the holder rotates in the upward/downward direction so as to adjust upward/downward deflection angle. And to bring down a body 4, the connection between the shaft 11 and the transverse lever 25 is released by working a clutch B and hereby the body is brought down while keeping the deflection angle of the mirror 8. Thereafter, when returning the body 4 to the normal position, the relation angle between the transverse lever 25 and the arm base 31 is kept as it was. Accordingly, it is needless to readjust the angle of the mirror 8 over again after the return of the mirror. |
