PURPOSE:To easily assemble and to reduce in size and thickness a motor by providing a side pressure eccentric groove on a bracket, inserting a bearing, then inserting an elastic member, and holding the member in the groove. CONSTITUTION:A bracket 3b is formed in a structure provided with a side pressure eccentric groove 20 on the outer surface of a cylinder, a lower bearing 10 is inserted, and an elastic member 19 is then inserted. The member 19 is held by the groove 20 of the bracket 3b, and a side pressure is applied by the partially exposed part of the bearing 10. With this structure it can be inserted into the bracket 3b without applying a load to the bearing 10, and the side pressure can be accurately applied by the member 19. Thus, it can be easily reduced in size and assembled. |
