A lock mechanism for a webbing retractor prevents an occupant restraining webbing from being wound off from a webbing takeup shaft when a vehicular emergency occurs. The lock mechanism is provided with a member to which the rotational force of the takeup shaft is transmitted through frictional contact and which cancels the locked state of the lock mechanism when the takeup shaft rotates in the webbing wind-up direction. Accordingly, it is possible to prevent the webbing from being gradually wound up when the vehicle is running thus avoiding any possibility of causing the webbing to undesirably tighten against the body of the occupant.
