Abstract

PURPOSE:To eliminate clearance sound of a motor in a simple structure by pressure-contacting a free end of a flat spring, with the other end fixed, with the forward end of a pinion fixed at a motor shaft or the top surface of the shaft. CONSTITUTION:A motor 1 includes a motor shaft 2, a motor pinion 3, and a flat spring 4, and a gear box is composed of a first gear 5, a lower case 6, a spacer 7, and an upper case 8. The flat spring 4 is energized from the top to the motor pinion 3 of resin to be fitted-in and fixed at the motor shaft 2, and the flat spring 4 is fitted-in and fixed at the lower case 6 by means of a spacer 7. By thus pressing the flat spring 4 to the top surface of the motor pinion, a component force in the side pressure direction is produced on the output shaft side of the motor shaft 2, thereby production of clearance sound of the motor 1 can be prevented.
