Abstract: A method of manufacturing an articulation prosthetic implement includes the steps of previously manufacturing a on-way clutch covered and fitted with a metal bush, the metal bush covered and fitted with a synthetic resin bush, and the synthetic resin bush covered and fitted with a brake bush; covering and fitting a rotary shaft of an outer member with flanges at either end, having a rotary shaft at the inner side and an annular depression around the rotary shaft, with the one-way clutch having the three bushes; fitting a cylindrical projection of an inner member having flanges at either end into the annular depression of the outer member located outside the brake bush; screwing or bolting a stopper for controlling the range of rotary shaft rotation to an inner projection of the rotary shaft; fitting one articulation protecting member of the articulation prosthetic implement to the flange of the inner member from the surface side of the inner member; and fitting the other articulation protecting member of the
