Abstract
When gas is generated in an emergency situation of a vehicle and a cylinder is driven, one of wires rotates a pulley via a small diameter portion of the pulley. For this reason, the other wire connected to a large diameter portion of the pulley has a length wound around the large diameter portion, which is longer than that of the one wire. A drive stroke of the cylinder is increased and transmitted to a seat belt buckle. As a result, even if the cylinder is of a small size, a long pulling stroke is applied to a seat belt.
