Claim:
A motor retractor, comprising: a winding shaft which winds up a webbing for restraining a vehicle passenger; a motor which rotates the winding shaft in a webbing winding-up direction; and a control portion which, after release of the webbing wearing state of the passenger: drives the motor to cause the webbing to be wound up around the winding shaft; stops the motor when an overload on the motor is detected during the winding-up; redrives the motor after a predetermined time having elapsed after the motor is stopped due to detection of the overload, and adjusts, at the time of the redriving, a driving state of the motor according to the time of driving the motor that has elapsed before the overload detection, wherein, when the time of driving the motor that has elapsed before the overload detection is equal to or longer than a preset time, the control portion lowers the magnitude of a supply current to the motor at the time of the redriving.
