ベルト巻取装置。[Claims for Utility Model Registration] 1. A frame fixed to a vehicle body, a seat belt take-up reel rotatably supported by the frame, and a seat belt take-up reel interposed between the take-up reel and the frame, A plurality of spring members having different spring forces for imparting rotational force in the belt winding direction to the reel, and a substantial fixed position of the spring members relative to the frame are changed, so that when the occupant properly wears the seat belt. In the seatbelt retractor, the seatbelt retractor is provided with a switching means for switching the seatbelt winding force acting on the takeup reel to a value smaller than the winding force when the seatbelt is normally retracted; A shape memory alloy spring whose apparent length changes when the temperature of A seatbelt retractor characterized in that it is provided with a blocking means for blocking a switching operation to the side. 2. The switching means is displaced by excitation of a spring case and a solenoid that are interposed between a plurality of spring members having different spring forces that are interposed in series between the frame and the take-up reel, and the switching means is displaced by excitation of a solenoid and a spring case that is interposed between a plurality of spring members having different spring forces that are interposed in series between the frame and the take-up reel. It consists of a redeuse lever that is fixed at the position of , and a switch that detects the connection between the tongue and the buckle engaging member provided at the pull-out end of the seat belt and energizes the solenoid, and the blocking means is a shape memory alloy spring. Due to the change in the apparent length of the lever, it engages with the redeuse lever at low temperatures,
The seat belt retractor according to claim 1, which is a cancel lever provided with a claw that prevents the redeuse lever from moving toward the fixed side of the spring case.
