Abstract
An operating load of an overload releasing mechanism is made to be high by a simple method. In a webbing retractor, spring claws engage with recesses of a rotor, and a gear wheel and the rotor are connected. When relative rotational force is applied between the rotor and the gear wheel, the spring claws elastically deform and engagement thereof with the recesses is released. Due thereto, connection of the rotor and the gear wheel is released, and the overload releasing mechanism is operated. Here, urging members urge the spring claws toward a side of engaging with the recesses. Due thereto, the operating load of the overload releasing mechanism can be made to be high by a simple method of merely adding the urging members.
