知機構付きリトラクター。[Claims for Utility Model Registration] (1) A retractor with a webbing winding amount detection mechanism that detects the webbing winding amount from the rotational speed of the retractor shaft that winds up the webbing, in which the rotation of the retractor shaft is controlled by a deceleration mechanism. and a rotary member rotatably provided with an actuator for actuating a switch according to the amount of rotation of the retractor shaft, and the actuator is configured to detect webbing winding amount. Rotates along the cam groove provided on the inner surface of the mechanism cover,
A retractor with a webbing winding amount detection mechanism characterized in that an actuator presses an operating piece of a switch when a rotating member rotates to a certain position. (2) A retractor with a webbing winding amount detection mechanism that detects the winding amount from the rotational speed of a retractor shaft winding the webbing, and a rotating member to which the rotation of the retractor shaft is transmitted via a speed reduction mechanism; An actuator for operating a switch according to the amount of rotation of the retractor shaft is slidably provided on the rotatable rotating member, and the actuator is connected to a cam provided on the inner surface of the cover of the webbing winding amount detection mechanism. The actuator is slidably fitted into the groove, and when the rotating member rotates to a certain position and the actuator is guided by the cam groove and slides outward from the rotating member, the actuator is activated by the switch. A retractor with a webbing winding amount detection mechanism that operates.
