Abstract
It is an object of the present invention to provide a motor having a structure so as to prevent the peeling off of adhesive for fixing the bearing. The outer ring of the second ball bearing is fitted into the second ball bearing fitting space of the bearing holder portion of the second end bracket. The annular leaf spring which gives a pressure in the direction toward the first end bracket to the outer ring of the second ball bearing is disposed in the pressure giving structure receiving space which is formed continuously to the second ball bearing fitting space. The annular leaf spring is shaped such that trough and crest portions appear alternately in the circumferential direction. The screw members are inserted into the screw holes formed in the second end bracket. The tip end portions of the screw members are arranged to abut the trough portions of the annular leaf spring.
