Abstract
In a webbing locking device locking an occupant restraining webbing, a movable locking member opposed to a fixed locking member is movable in a direction of a webbing drawing-out and approach to the webbing and trigger means causes the webbing to abut on a portion of the movable locking member, so that the webbing is locked by the fixed and movable locking members.
In the locking of the webbing a webbing drawing-out force is converted to a locking, or clipping, force of the webbing by the movable and fixed locking member.
