A motor, in which a creep phenomenon can be prevented and a ball bearing can readily be mounted, is provided. A pair of end brackets each have a bearing hole in which a ball bearing is fitted. A pair of ball bearings are fitted into the bearing holes of the end brackets such that an outer race portion of each ball bearing may abut on a first wall surface and a second wall surface of the end bracket. A stopper fitting is pushed into a recessed portion of the end bracket until a ring portion of the stopper fitting abuts on the outer race portion of the ball bearing. Six engaging pieces of the stopper fitting are engaged in a fourth wall surface defining the recessed portion due to a restoring force of the engaging pieces, which have been resiliently bent or warped, to restore from the bent or warped state. Thus, each ball bearing is tightly fixed in the bearing hole by means of the stopper fitting. |
