Claims

[Scope of utility model registration request]

A take-up shaft that winds up one end of the occupant restraint webbing, a lock ring that is supported coaxially with the take-up shaft and causes a rotation delay with respect to the take-up shaft in an emergency state of the vehicle, and a lock ring that is supported by the take-up shaft and that is supported on the take-up shaft. a lock member that is movable relative to the take-up shaft from a first position to a second position and prevents rotation of the take-up shaft in the webbing unwinding direction in the second position; a pin protruding from the lock member; and the lock member. a long hole provided in the ring and capable of accommodating the pin;
a guide means for guiding the lock member to the first position and the second position; and a biasing means that comes into contact with the pin and urges the pin toward one end of the elongated hole to hold the lock member at the first position. Device.
