Abstract
An anchoring device includes an insertion member having a trough-shaped trunk and a pocket provided at the front end of the trunk. A plate nut is inserted in the pocket and formed with a threaded hole at its portion protruding from the pocket. A seat member is fitted around the trunk. An engaging rib is formed on the inner surface of the seat member. A plurality of steps are formed on the outer surface of the trunk and arranged in the longitudinal direction of the trunk. When the seat member is moved toward the front end of the trunk, the engaging rib engages the respective steps one after another, thereby preventing the seat member from moving toward the rear end of the trunk. Any step nearer to the rear end of the trunk is smaller than any step nearer to the front end of the trunk.
