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.

Abstract: A rotary apparatus includes a motor including a rotary shaft, a plurality of gears including an output gear, and a housing accommodating the motor and the plurality of gears. The housing is separable into a first housing and a second housing. The motor includes a first end portion and a second end portion located on an opposite side of the first end portion. The rotary shaft is derived from the first end portion. The second housing includes a first regulating portion regulating a position of a part of the motor on the first end portion. The first housing includes a projecting portion projecting toward the second housing side. The projecting portion urges the second end portion of the motor toward the first regulating portion side directly or via another member.
