Abstract: A motor according to an embodiment includes a commutator provided to a rotation shaft, a brush in contact with the commutator, a bracket having a wall surface opposing the brush, and a deformable portion in contact with the brush and the wall surface. The bracket includes a protrusion provided on the commutator side with respect to the deformable portion. The protrusion protrudes from the wall surface toward the brush.

Abstract: A motor includes an armature including a commutator, a bracket including a conductive brush and a first wall part, and a first deformable part. The conductive brush is in contact with the commutator. The first wall part includes a first surface extending along a first surface of the conductive brush. The first deformable part is in contact with both the first surface of the conductive brush and the first surface of the first wall part. The first deformable part is deformable in response to movement of the conductive brush.

Abstract: A motor includes a commutator, a bracket including a conductive brush, first and second wall parts, and first and second deformable parts. The conductive brush is in contact with the commutator. The first wall part includes a first surface extending along a first surface of the conductive brush. The second wall part includes a second surface extending along a second surface of the conductive brush located on a side opposite the first surface of the conductive brush. The first deformable part is in contact with both the first surface of the conductive brush and the first surface of the first wall part, and is deformable in response to movement of the conductive brush. The second deformable part is in contact with both the second surface of the conductive brush and the second surface of the second wall part, and is deformable in response to movement of the conductive brush.
