ABSTRACT:
In a webbing take-up device, when the release of a webbing belt is detected from the signal of a buckle switch, a motor starts driving, the webbing belt is taken up, and a computing circuit increases a voltage Eb in accordance with an integrated time after the signal is switched. In this state, a lock current flows due to an output shaft of the motor being stopped, and when the power to the motor is cut off by increasing the lock current, the values of voltages El and Ed respectively corresponding to the integrated time in which the lock current is powered and the integrated time in which the power to the motor is cut off are subtracted from the value of the voltage Eb, and the motor is driven until the computing result reaches a predetermined value.
