Provided are a seat belt retractor and a seat belt apparatus, which can reduce the emanation of abutment noise upon switching of a clutch. A first embodiment of a seat belt retractor according to the present invention includes a spool for retracting a webbing W to restrain an occupant, a motor for generating drive torque to rotate the spool, a power transmission means for transmitting the drive torque of the motor to the spool, a clutch for connecting or disconnecting the power transmission means and the spool, and a casing for housing the clutch and the power transmission means. The clutch has a pawl rotatably connected to the casing, an actuating pin for rotating the pawl in conjunction with the power transmission means, and a stopper portion for limiting the rotation of the actuating pin.
