SEAT BELT RETRACTOR

摘要

A seat belt refractor capable of easily assembling a torsion bar of an energy absorbing mechanism and a ratchet wheel of an emergency lock mechanism under a specified phase of angle to eliminate the deviation of synchronization in order to absorb an energy effectively, wherein a connection part (5b) of the torsion bar (5) to the ratchet wheel (41) and a fitting hole (41c) on a ratchet wheel (41) side into which the connection part (5b) is fitted pressingly are formed in a polygonal cross-section with recesses and projections formed at specified intervals in circumferential direction, and ribbed projections (8) which bias the torsion bar (5) in the fitting hole (41c) in the rotating direction at the time of withdrawal of a webbing and press their mutual recessed and projected fitting hole (41c). <IMAGE>
