Abstract
A motor includes a motor unit, a deceleration unit, and a connector unit. The motor unit outputs rotational drive force and includes a yoke housing, a commutator, a power supply brush, a conductive member, and a brush holder. The yoke housing has an open end in an axial direction. The conductive member is electrically connected to the power supply brush. The brush holder is arranged in the open end to hold the commutator, the power supply brush, and the conductive member. The deceleration unit includes a gear housing coupled to the open end. The connector unit is coupled to the gear housing and including a connection terminal electrically connected to the conductive member. The commutator and the power supply brush are arranged outside the yoke housing. The conductive member and the yoke housing are arranged on opposite sides of the commutator.
