Brush device and motor

The invention provides a brush device (31) and a motor (1) capable of suppressing rattling of a brush (33) without increasing the number of parts. A brush holder (32) extends substantially in a radial direction of a commutator (16). The brush holder (32) includes a first inner side surface (S1) and a second inner side surface (S2), which are separate from each other in the axial direction of the commutator (16). A torsion spring (34) presses portions-to-be-pressed (P4, P5) of a brush-rear end (33n), thereby urging the brush (33) toward the commutator (16). The portions-to-be-pressed (P4, P5) are deviated from a brush-center line (L2) in the axial direction of the commutator (16). The brush (33) is urged by the torsion spring (34), thereby bringing a brush-tip end (33m) into contact with the first inner side surface (S1), and bringing the brush-rear end (33n) into contact with the second inner side surface (S2).
