Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a motor capable of improving workability of a work for forming a deformation member between a conductive brush and a wall part.SOLUTION: A motor 10 comprises: a commutator 33; conductive brushes 42 and 43 contacted with the commutator 33; a bracket 40 on which the conductive brushes 42 and 43 are provided; first wall parts 62 and 63 provided on the bracket 40, and that have first surfaces 62a and 63a extending to the commutator 33 side along first surfaces 42b and 43b of the conductive brushes 42 and 43; and first deformation parts 72 and 73 contacted with the first surfaces 42b and 43b of the conductive brushes 42 and 43 and the first surfaces 62a and 63a of the first wall parts 62 and 63, and that deform depending on movement of the conductive brushes 42 and 43. A part of the first surfaces 62a and 63a of the first wall parts 62 and 63, where the first deformation parts 72 and 73 are contacted, comprises first recessed parts 62b and 63b. The first recessed parts 62b and 63b have one or more first recesses depressed to the inside of the first wall parts 62 and 63.SELECTED DRAWING: Figure 5
