ング巻取装置。 A webbing take-up shaft, an elastic body that weakly biases the webbing take-up shaft in the webbing take-up direction, a motor, and a centrifugal force generated by the rotation of the motor that is connected to the webbing take-up shaft and transmits the rotational force of the motor to the webbing take-up shaft. The centrifugal clutch has an axially moving body that moves in the axial direction and connects with the webbing take-up shaft, and a centrifugal clutch that converts the centrifugal force into the axial force and transmits the force to the axially moving body. A webbing take-up device comprising a centrifugal force drive means for moving the webbing take-up device in an axial direction.
