description A motor housing includes a bearing holder that holds a first bearing and accommodates a rotor and a stator. A second bearing is disposed inside a motor shaft at one axial end portion of the motor shaft and has lower electric resistance than the first bearing. The conductive member electrically connects the second bearing to a motor housing. The radially outer end portion of the second bearing is in contact with the inner peripheral surface of the motor shaft. The contact portion of the conductive member is in contact with the radially inner end portion of the second bearing. The fixed portion is fixed to the motor housing radially outward of the motor shaft. A bridge portion connects the contact portion and the fixed portion.
