When deceleration in excess of a predetermined value acts upon a vehicle and/or when a seat belt is pulled at an acceleration in excess of a predetermined value, lock actuating means sets a state in which a first engaging member supported on a reel shaft is capable of engaging a first engaged portion of a frame, thenceforth sets a state in which a second engaging member supported on the reel shaft is capable of engaging a second engaged portion of the frame, and then engages the first engaged portion an the first engaging member as Well as the second engaged portion and the second engaging member. As a result, engagement between the first engaged portion and the first engaging member and between the second engaged portion and the second engaging member is performed in reliable fashion.
