ABSTRACT:
A webbing retractor for winding a webbing which is fastened around a seat occupant of a vehicle is arranged such that a claw member is engaged with a ratchet wheel fixed to a webbing take-up shaft and rotation of the take-up shaft in a direction in which the webbing is drawn out is thereby prevented when the speed of the vehicle suddenly reduces. Engagement of the claw member with the ratchet wheel is achieved by engaging a rotary wheel which is rotated in the same direction as that in which the take-up shaft is rotated with a driving plate which drives the claw member to cause it to be engaged with the ratchet wheel through a cam ring and an engaging lever. In consequence, the rotational force of the rotary wheel is reliably transmitted to the driving plate by means of the cam ring and the engaging lever.
