。[Claims for Utility Model Registration] 1. A base; a take-up shaft rotatably supported by the base and biased in the webbing take-up direction; a locked member that rotates integrally with the take-up shaft; It is movably supported by the base between a locked position and an unlocked position according to the webbing winding diameter on the take-up shaft, and engages with a locked member in the locked position to rotate the take-up shaft in the webbing pulling direction. a locking member that prevents the locking member from engaging with the locked member in the unlocked position and allows free rotation of the winding shaft; a biasing member that urges the locking member toward the engaged position; It has an action part that is formed in a part that rotates integrally with the take-up shaft and faces the webbing take-up direction; an action part and an engagement part, and the action part engages with the locking member to cause the locking member to move. It is movable between a non-operating position in which it moves in the webbing pull-out direction, which prevents movement to the engaged position, and an activated position, in which it moves in the webbing retracting direction, which allows this movement, and the engaging part is in contact with the acting part. It is movable between an engaged position where the actuating force is applied from the acting part toward the operating position when the take-up shaft rotates in the webbing take-up direction, and a non-engaged position where the actuator is not engaged. an actuating member provided on the base; a first biasing means for biasing the actuating member toward the non-operating position; and a biasing force weaker than the first biasing member toward the non-engaging position; A self-locking type device characterized by having a second biasing means for biasing with force; and a guide means for guiding the operating member between an inoperative position and an operating position and between an engaged position and a non-engaged position. Retractor. 2. The tractor according to claim 1, wherein the acting portion is formed on the locked member. 3. Utility model registration claim 1, in which the first and second biasing means are plate spring parts integrally formed with the actuating member.
Tractors listed in section. 4. The tractor according to claim 1, wherein the guide means includes a hole formed in the base for regulating the movement range of the actuating member and a protrusion of the actuating member extending into the hole.
