ラクター。[Claims for Utility Model Registration] (1) A ratchet wheel that rotates integrally with the webbing take-up shaft and has a plurality of teeth formed on its outer periphery, and a base that rotates toward and away from the ratchet wheel. an arm that is pivotally mounted and biased toward or away from the ratchet wheel by a spring; and an arm that is rotatably supported by the arm and that can engage the teeth of the ratchet wheel. A pawl includes a mating pawl and a guide pin, and the pawl is biased in a direction in which the mating pawl engages the teeth of the ratchet wheel, and the pawl is frictionally engaged with the ratchet wheel and has guide pins at both ends. A pair of protrusions are formed in the intermediate portion to rotate the arm so that the direction in which the arm is biased by the spring is opposite, and the engagement pawl is engaged with the teeth of the ratchet wheel depending on the direction of the arm. A seatbelt retractor comprising a cam plate having a guide path for a guide pin formed in a recessed portion for mating. (2) A cover is further provided, and the cover includes a stopper for preventing the engaging pawl from joining each tooth of the ratchet wheel when the arm is oriented in such a state that the engaging pawl cannot engage the teeth of the ratchet wheel. A protruding seat belt retractor according to claim 1 of the utility model registration claim. (3) Further, a stopper movable between a position that prevents and a position that allows movement of the arm to a position where the engaging pawl of the pawl can engage the teeth of the ratchet wheel; A seat belt retractor according to claim 1 or 2, which is provided with a solenoid for moving the seat belt.
