A webbing take-up device including: a spool; a rotating member configured such that the spool is rotated in a take-up direction by the rotating member being rotated toward one side; a cylinder open at an axial direction leading end side; a fluid supplier provided at an axial direction base end side of the cylinder and supplying a fluid inside the cylinder in a vehicle emergency; a moving member provided inside the cylinder, moved toward the axial direction leading end side of the cylinder due to pressure of the fluid, and rotating the rotating member toward the one side by being moved in a state in which a tooth of the rotating member has bitten into or pierced the moving member; and a stopper provided further toward a movement direction side of the moving member than a section where the tooth of the rotating member has bitten into or pierced the moving member, the stopper being pressed by a portion of the moving member where the biting into or piercing of the rotating member has been disengaged, the stopper being engaged by teeth of the rotating member, and the stopper suppresses rotation of the rotating member toward the one side by the stopper being moved toward the section where teeth of the rotating member bite into or pierce the moving member.

Webbing take-up device

In a webbing take-up device, side faces of press-fit holes in a pinion are inclined in directions toward the outside of the press-fit holes on progression toward the right. Press-fit portions of a torsion shaft are press-fit into the press-fit holes from the right such that an interference force between the press-fit portions and the side faces of the press-fit holes increases on progression toward the left. This enables the press-fit portions to be effectively retained in the press-fit holes.
