A webbing retractor includes a spool, a motor, a force limiter mechanism, a first rotating body, a second rotating body, a ratchet gear, a pawl body and a control section. The ratchet gear is provided at one of the first rotating body or the second rotating body. The pawl body is provided at another of the first rotating body or the second rotating body. The pawl body can engage with the ratchet gear in a case in which the first rotating body rotates toward one side, and engagement of the pawl body with the ratchet gear being cancelled in a case in which the first rotating body rotates toward another side. The control section drives the motor to rotate in reverse, such that the first rotating body rotates toward another side in a case in which a physical amount relating to load of the passenger exceeds a predetermined value during forward rotational driving.
