Patent ID: 8292208

Claim:
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, wherein the holding member has load receiving portions formed in a flat plate shape, external force for mounting the holding member to the frame by passing the leg portions through the hole portions respectively being imparted at external force receiving positions of the load receiving portions, the external force receiving positions being set at positions each between a connecting portion connecting the pair of leg portions at a side opposite to the wall portion with respect to the pretensioner and a holding position of the leg portion in contact with the pretensioner to hold the pretensioner.
