PROBLEM TO BE SOLVED: To provide a motor device capable of achieving further reduction in weight by establishing a structure capable of coping with resinification of a gear case.SOLUTION: Between a motor case 21 and a ball bearing 28, a stopper plate 60 is provided which presses the ball bearing 28 into a gear case 31. The stopper plate 60 is avoided from being inserted into and fixed to the gear case 31, and a pressing force of the stopper plate 60 can be prevented from being directly acted on the gear case 31. Accordingly, even if the resin-made gear case 31 is employed, the gear case 31 can be inhibited from being creep-deformed. Therefore, further reduction in weight is made possible by establishing a structure capable of coping with resinification of the gear case.31. |
