タ。[Claims for Utility Model Registration] 1. A winding shaft means biased in the belt winding direction and rotatably supported by the base member, and a lock for locking rotation of the winding shaft means in the belt pulling direction. and a vehicle body sensing mechanism that uses a weight to sense a change in speed of the vehicle that exceeds a predetermined value and causes a locking mechanism to lock the rotation of the winding shaft means in the belt withdrawal direction through an actuating member that engages with the weight. In the emergency lock type retractor, the retractor is interlocked with the take-up shaft means within a predetermined movement range, and when the take-up shaft means rotates in the belt winding direction, it assumes a regulating position within the predetermined movement range and engages the actuating member. The actuating member and the weight are held in a state in which a speed change exceeding the predetermined value is not detected, and when the winding shaft means rotates in the belt pulling direction, the actuating member and the weight are held in a non-restricted position within the predetermined movement range. An emergency lock type retractor characterized by being provided with a regulating member that does not act on the operating member. 2. The retractor according to claim 1, wherein the winding shaft means and the regulating member are in an interlocking relationship due to magnetic action. 3. The winding shaft means and the regulating member are in an interlocking relationship due to frictional action.
Retractor as described in section. 4. The retractor according to claim 1, wherein the actuating member is a sensor arm for transmitting a sensing signal from a weight to the locking mechanism.
