ABSTRACT:
A lock ring journalled on a takeup shaft for winding an occupant restraining webbing is adapted to guide a plurality of lock plates provided around the takeup shaft in directions opposite to each other, and an engageable device subjected to a turning force of the takeup shaft in an emergency situation of a vehicle drives the lock plates in directions opposite to each other due to a lag in rotation of the lock ring from the takeup shaft and pushes the lock plates against an internally toothed ratchet wheel to thereby stop the takeup shaft from rotating in the webbing unwinding direction.
