Abstract
Provided is a webbing winding device capable of mounting a holding member for holding a pretensioner on a frame easily. The webbing winding device has a holder which is mounted on a leg plate only by applying loads to tip ends (upper ends) of load receiving pieces and pushing the tip end (bent portion) sides of engagement claws into hole portions. With this structure, the operation of mounting the holder on the leg plate is easy and does not need any component such as screw. As no fastening component such as screw for mounting the holder on the leg plate is required, the cost for components is reduced and as no fastening step of screw is required, such cost is also reduced.
Claims12
A webbing winding device comprising:
- a spool that is connected to a base end side in a longitudinal direction of a webbing belt formed in a longitudinal band shape and that winds up the webbing belt from the base end side in the longitudinal direction to accommodate the webbing belt;
- a pretensioner that imparts to the spool a rotational force in a direction of winding the webbing belt by activation thereof;
- a frame that rotatably supports the spool directly or indirectly, the frame having a wall portion where the pretensioner is disposed to face the wall portion, and a pair of hole portions whose distance therebetween along a predetermined direction parallel to a wall surface of the wall portion facing the pretensioner corresponds to a dimension of a predetermined portion of the pretensioner along the predetermined direction;
- and
- a holding member formed in a substantially U-shape opening toward the wall surface and having a pair of leg portions, a distance between the pair of leg portions corresponding to the dimension of the predetermined portion of the pretensioner along the predetermined direction, the holding member holding the pretensioner with the wall portion by the pair of leg portions being engaged with the pair of hole portions respectively.

- and
- a holding member formed in a substantially U-shape opening toward the wall surface and having a pair of leg portions, a distance between the pair of leg portions corresponding to the dimension of the predetermined portion of the pretensioner along the predetermined direction, the holding member holding the pretensioner with the wall portion by the pair of leg portions being engaged with the pair of hole portions respectively,
- wherein the holding member includes a connecting portion connecting the pair of leg portions, and the holding member holds the pretensioner by sandwiching the pretensioner with the connecting portion and the wall portion and sandwiching the pretensioner with the pair of leg portions, and
- the pair of leg portions are inserted into the pair of hole portions respectively from a side opposite to the wall portion with respect to the pretensioner.
