Claims

[Scope of utility model registration request]

A take-up shaft for winding the webbing, a take-up shaft biasing means for urging the take-up shaft in the webbing winding direction, and a take-up shaft biasing means arranged coaxially with the take-up shaft and capable of rotating independently of the take-up shaft. a rotating body, a rotating body biasing means supported by the take-up shaft and urging the rotating body in the webbing unwinding direction;
The first gear, which is arranged coaxially with the winding shaft and rotates together with the winding shaft, is different from the first gear, which is pivotally supported by the rotating body and meshes with the first gear. A second gear of the number of teeth is provided on each of the first gear and the second gear and is brought into contact with each other to prevent relative rotation of the first gear and the second gear in one direction. a webbing take-up amount limiting means that allows multiple rotations of the first gear in the opposite direction, a rotating body rotation preventing means that engages with the rotating body to prevent rotation of the rotating body, and a rotating body rotation preventing means. A rotating body rotation prevention means biasing means for urging the means in a direction to engage with the rotating body, and a rotating body rotation prevention means that is engaged with the rotating body by frictional force and is used to unwind the webbing immediately after webbing is attached through the rotating body. a first cam means which is rotated by the rotating body to control the engagement of the rotating body rotation prevention means with the rotating body; and a first cam means which is engaged with the first cam means and is engaged with the first cam means for unwinding the webbing and subsequently attaching the webbing. a second cam means that is rotated via the first cam means when the webbing is immediately taken up and controls the engagement of the rotating body rotation prevention means with the first cam means; and a state in which the webbing is attached or a sheet. When the door of a vehicle equipped with a belt device is closed, the rotating body rotation preventing means is enabled to engage with the rotating body, and the rotating body rotation preventing means is engaged with the rotating body in conjunction with the opening operation of the door or the uninstalling operation of the webbing. A webbing retractor for a seat belt device, comprising a rotating body rotation preventing means moving means for releasing engagement with the rotating body.
