Claims (1)

[Scope of utility model registration request] The driving force of the drive unit engages the pawl lever with the latch gear that rotates together with the take-up shaft, and prevents the take-up shaft from rotating in the webbing winding direction, thereby reducing the tension applied to the webbing when the webbing is properly attached by the occupant. A webbing retractor capable of cutting the webbing, which includes a position information detecting means for detecting position information as the take-up shaft rotates, and a maximum retracting position that determines the maximum webbing retracting position information when the webbing is attached. an information setting means, a comparison means for comparing the maximum winding position information with position information in a tension cut release state detected after a predetermined time has elapsed from the setting of the maximum winding position information, and a comparison by the comparing means. Judgment means for judging whether the tension cut position information set by the setting means is suitable for the occupant to wear webbing based on the result;
A webbing retractor having a webbing retractor.
