A seatbelt retractor for winding a seatbelt includes a spool for winding the seatbelt, a motor for generating rotational torque to rotate the spool, and a clutch mechanism. The clutch mechanism connects a power transmission path to transmit the rotational torque of the motor to the spool in a connected mode, and disconnects the power transmission path in a disconnected mode. A noise preventing device prevents noise when the clutch mechanism is in the disconnected mode.
