1. A motor comprising:
a commutator;
a first conductive brush including a first surface and an opposite second surface, the second surface including a part in contact with the commutator; and
a bracket including a first wall part; and
a first deformable part being in contact with the first surface of the first conductive brush and a surface of the first wall part in a circumferential direction, wherein
the first deformable part is formed with a gel having a volume, resin having a volume or grease having a volume,
the part of the first conductive brush in contact with the commutator extends in a long direction of the first conductive brush toward the commutator,
the surface of the first wall part is inclined with respect to the first surface of the first conductive brush, and
a distance between the surface of the first wall part and the first surface of the first conductive brush on a commutator side of the first conductive brush is less than a distance between the surface of the first wall part and the first surface of the first conductive brush on a root side of the first conductive brush.
