ABSTRACT OF THE DISCLOSURE A first and a second springs are connected in series to a take-up shaft of a seatbelt so as to generate wind-up force; when the seatbelt is put on by an occupant, a pawl is engaged with a latch gear provided at a connecting portion between said springs, whereby the biasing of only one of said spring is imparted to the take-up shaft, thereby decreasing the wind-up force of the take-up shaft; after the seatbelt is released from the occupant, the pawl is disengaged from the latch gear by a camplate means connected to the take-up shaft through a one-way clutch, by which the wind-up force of the take-up shaft is imparted when the relative rotation between the camplate and the take-up shaft is more than one thirds of a turn, whereby the wind-up force of the take-up shaft is increased and the condition where the wind-up force is maintained at a low level even when the occupant moves his body with the seatbelt being worn by the occupant.
