Wires (9) which are introduced from an operation rod into a mirror housing (5) to adjust the swinging of a mirror (8) are tensioned to a certain extent by a wire slack preventing means, which is located in the mirror housing (5), to precisely act the mirror without being loosened. Tubes (37) through which the wires (9) are inserted are positonally defined in a base (2) and fixed shaft (3) to precisely guide the wires (9). |
