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 biasing 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 preventing means biasing means for urging the means in a direction to engage with the rotating body, a rotating body rotation preventing means control rod connected to the rotating body rotation preventing means, and a rotating body rotating body and a friction force A cam part that is engaged and rotated via the rotating body and guides the rotating body rotation blocking means control rod, and a stopper part that can prevent the rotating body rotation blocking means from engaging with the rotating body. When the webbing is attached or the door of a vehicle equipped with a seat belt device is closed, the rotating body rotation preventing means control body is placed in a state where the rotating body rotation preventing means can be engaged with the rotating body, and the door is opened. A webbing for a seat belt device, comprising a rotating body rotation preventing means moving means for releasing the engagement of the rotating body rotation preventing means with the rotating body in conjunction with the operation or the webbing release operation. Winding device.
