Abstract
A webbing take-up device provided with a clutch disposed between a take-up shaft and a motor, the clutch coupling and releasing coupling of the take-up shaft to the motor. When a gear wheel of the clutch is rotated in a take-up direction by the motor, a friction spring mounted to a spring housing portion of the clutch housing moves a pawl with a first protrusion of the friction spring, causing the pawl to mesh with a ratchet wheel. Relative rotation of the gear wheel with respect to the ratchet wheel (spool) in the take-up direction is thereby restricted, and the spool rotates with the gear wheel in the take-up direction. Since the pawl is directly moved by the friction spring mounted on the clutch housing, the configuration for moving the pawl can be simplified.
