The limb joint device comprises: a drive disc; a driven disc; a joint pin extending through the individual centers of the drive disc and the driven disc. The drive disc is detachably attached to one of the adjoining body protecting members and includes an outer flange, and an inner flange disposed radially inside of the outer flange and defining an annular groove in the end face of the drive disc together with the outer flange. The outer flange is formed with a through hole extending in a tangential direction of the annular groove. The driven disc is detachably attached to the other of the body protecting members and formed with such a raised segment at the end face confronting the drive disc as to engage in a sliding manner with the annular groove of the drive disc. Further comprised is a turning motion regulating pin inserted into the through hole to come into and out of the annular groove, for regulating the turning motions of the raised segment in the annular groove.
