Abstract

PROBLEM TO BE SOLVED: To prevent a crank mechanism from being broken when external force is applied to the crank mechanism by connecting the output shaft of a reduction gear driven by a motor through the crank mechanism and by interposing a plate spring at an intermediate part of the crank mechanism. SOLUTION: A first arm 6 is fixed at the tip of the output shaft of a reduction gear, and a second arm 7 is fixed to the first arm 6 through a plate spring 5. A third arm 8 is rotatably connected to the second arm 7, and the lower end of the third arm is fixed to a fourth arm 9 fixed to a reflector 4. The torque of the output shaft is applied to the fourth arm 9 to rotate the reflector 4 in a vertical plane. The reflector 4 is rotatably supported at both lower ends of a substantially U-shaped arm 11 supported by a case 10 having a motor built in. Thereby, the first to fourth arms 6-9 constituting a crank mechanism 3 may hardly be broken by virtue of a damping action caused by the plate spring 5 even if external force is applied to the crank mechanism 3.

The third arm 8 is rotatably connected to the second arm 7, and the lower end of the third arm 8 is fixed to the fourth arm 9 fixed to the reflector 4. Then, the rotational force of the output shaft 2a is applied to the fourth arm 9, and the reflector 4 can rotate in a vertical plane. The reflector 4 is rotatably supported at both lower ends of a substantially U-shaped arm 11 supported by a case 10 in which the motor 1 is built.
