PURPOSE:To make a device resettable so easily only in switching on a motor, by installing a power transmitting mechanism transmitting output of the motor, which is locked to a frame and rotates in time of resetting a second spiral spring, to a reset gear. CONSTITUTION:When the setting of a seat belt is set free, a take-up shaft 14 is rotated by a tightening spiral spring 26 and a take-up spiral spring 20, winding up a seat belt 16. The tightening spiral spring 26 comes into a state of being rotated a turn from a state of so far being set, while a lock lever 36 and a trigger lever 40 both rotate by energizing force of a lock lever reset spring 42 and a trigger lever reset spring 44, and again a pawl 36a of the lock lever 36 and a notch 50a of a flange 50 are engaged with each other, winding up the seat belt 16 with only the turning force of the take-up spiral spring 20. Therefore, a state of coupling between a clutch engager 56 and a gear 54 is released free. |
