To provide a seatbelt retractor not only capable of reducing the load on a motor related to clutch operation, thereby achieving downsizing and extending the life of the motor, but also enabling quick clutch release.SOLUTION: A power transmission mechanism 5 of a retractor 1 includes a clutch mechanism 10 that enables power to be transmitted from a motor 4 to a spindle 3 when the motor 4 rotates in a first direction (an arrow 100). The clutch mechanism 10 is configured to: when the motor 4 rotates in the first direction by a first number of rotations, switch from a clutch OFF state into a clutch ON state: and meanwhile, when the motor 4 rotates in a second direction (an arrow 200) opposite to the first direction by a second number of rotations that is smaller the first number of rotations, or when the motor 4 stops, switch from the clutch ON state into the clutch OFF state.SELECTED DRAWING: Figure 4
