Rotary joint of articulation prosthetic implement having rotating load setting means, articulation prosthetic implement using the rotary joint and method of making articulation prosthetic implement

A manufacturing method for an articulation prosthetic implement having a rotating load setting means, comprising the steps of previously manufacturing a one-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, and 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, followed by 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, subsequently 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 articulation prosthetic implement to the flange of the outer member from the surface side of the outer member.
