PURPOSE: To prevent a noise produced due to enlarging width of vibration by resonance, by changing power transmission from a motor to either one of a first gear row or a second gear row whose speed reduction ratio is different from each other according to the rotational direction of the motor by a gear mechanism. CONSTITUTION: When a motor M is rotated in a clockwise direction, a rotary gear (g2) is rotated in a counterclockwise direction through a motor gear (g1). Hereby, an arm member 3 is rotated in the counterclockwise direction centering around a shaft part 2. When a revolution gear (g3) is engaged with a gear (g4), the rotation of the revolution gear (g3) is transmitted to a roller gear (g7) through a first gear row 6 so that the roller gear (g7) is rotated in the clockwise direction. Meanwhile, when the motor M is rotated in the counterclockwise direction, the arm member 3 is rotated in the clockwise direction until the revolution gear (g3) and a gear (g8) are engaged with each other. The rotation of the revolution gear (g3) is transmitted to the roller gear (g7) through a second gear row 7, and the roller gear (g7) is rotated in the clockwise direction at a speed different from that of the first gear row 6.
