A webbing retractor has two torque transmitting routes for taking-up, such that rapid and reliable taking-up, and gentle taking-up are possible. When an engaging claw of a pawl restricts rotation of a ratchet plate, due to planetary gears rotating around a sun gear, rotation is transmitted from a drive gear to a carrier plate. On the other hand, when restriction of rotation of the ratchet plate is released, a clutch spring tightens around a tube portion of the carrier plate while rotation of the drive gear pulls one peripheral direction end of the clutch spring in a direction of rotation thereof. Frictional resistance between the tube portion and the clutch spring is increased, and rotation is transmitted from the drive gear to the carrier plate.
