Webbing Winding Device, Webbing Winding Method, and Vehicle

摘要

An amount of webbing that is pulled-out after operation of a pretensioner mechanism is reduced. In a webbing retractor 10, a lock pawl 78 is set in a non-meshable state in which it cannot mesh with a lock gear 26. At a time when a pretensioner mechanism 34 operates and a clutch plate 42 rotates in a take-up direction, a lock stopper 86 rotates together with the clutch plate 42 and releases engagement with the lock pawl 78. Therefore, the lock pawl 78 is rotated by a compression coil spring 70 and changed to a meshable state. In this way, immediately after rotational force in a pull-out direction is applied to the lock gear 26 due to load from a vehicle occupant after operation of the pretensioner mechanism 34, the lock pawl 78 meshes with the lock gear 26, and pulling-out of a webbing 20 is impeded. Therefore, an amount of the webbing 20 which is pulled-out can be reduced.
