PURPOSE:To simplify the structure and ensure the operation in a captioned device by connecting a mirror body with an operation part by a joint which works differently according to hinges and directions and fitting a mirror housing to a base to be rotatable round one of two axes of impulsive forces. CONSTITUTION:For shifting a mirror 1 vertically as arrows D and D' show, an operation part 61 is operated as arrows B and B' show. This operation moves a catch part 68 via a joint 63 as arrows A and A' show, and then inclines a mirror body 2 round a ball member 33 via hinges 64 and 65 as arrows F and F' show. Consequently, the mirror 1 is inclined as arrows D and D' show. Meanwhile, for shifting the mirror 1 horizontally (vertically to the figure), when the operation part 61 is operated horizontally (vertically to the figure), the mirror is inclined horizontally similarly as above. Besides, when an impulsive force is given to the mirror 1 as an arrow I shows, a concave part 32 of a mirror housing 3 is released from a convex part 42 of a base 4 in a fitting part J, and the mirror housing 3 is inclined round a fitting part K. A reverse process is given against a force shown by an arrow I'. |
