Abstract
A webbing take-up device including: a spool; a tube-shaped cylinder; a fluid supply unit; a rotating member including thrust teeth in a radial pattern about a rotation central axial line formed to faces that oppose one another in an axial direction, and including a tapered portion formed to a rotation outer peripheral side end portion of each of the thrust teeth and having a rotation axial direction dimension that decreases on progression toward a rotation radial direction outside, the spool being rotated in the take-up direction by the rotating member rotating toward one side; and a moving member that is moved toward the axial direction leading end side of the cylinder under pressure of the fluid to cause the rotating member to rotate toward the one side by being moved in an engaged state with the thrust teeth of the rotating member.
