  • a controller for controlling a motor that provides a force for retracting a seatbelt;

    a sensor that detects a motor current of the motor;

    wherein the controller is configured to determine whether or not the seatbelt is jammed during a seatbelt take-up operation on a basis of whether or not the motor current detected by the sensor exceeds a threshold value for jamming determination; and

    a detector that detects an indicator of a current versus load characteristic of the motor;

    wherein the controller is configured to set the threshold value for jamming determination on a basis of the indicator detected by the detector.
