In a webbing retractor, due to a moving member being moved toward an axial direction distal end side, and first teeth and second teeth of a rotating member piercing the moving member, the rotating member is rotated in a take-up direction. Here, at the moving member, a sectional surface area, in a direction orthogonal to an axis, of a small diameter portion that is at an axial direction distal end side is made to be small as compared with a moving member main body that is at an axial direction proximal end side. Therefore, resistance to movement of the moving member can be reduced.
