PROBLEM TO BE SOLVED: To improve operability at the time of adjusting a mirror by obtaining a mirror angle adjustment mechanism where a machine screw is rotated by inserting a driver in a direction in parallel with a mirror surface. SOLUTION: The mirror angle adjustment mechanism is provided with an end plate 25, a housing 21 movably fitting the end plate 25 so as to make it movable, a pressing member 29 disposed between the casing 21 and the end plate 25 and pressing the end plate 25 in a press-contacting direction by being brought into press-contact with one surface of the end plate 25, a fan-shaped member 31 freely rotatably held by the casing 21 in a circular-arc direction and making one radius part abut on the other surface of the end plate 25 and the machine screw 35 freely rotatably supported by the housing 21 and making a top end abut on the other radius part of the sectorial member 31. |
