ABSTRACT:
A wire guide apparatus for a wire driven mechanism includes an arm stem member, an arm end member having a hand section, a joint section for rotatably coupling the arm end member to the arm stem member, a wire guide pulley, and a device for bending the arm end member relative to the arm stem member. The arm stem member is provided with a first drive source for driving the hand section via wires and a second drive source for driving the bending device. The wire guide pulley is rotatably supported at an eccentric position relative to an elbow position of the arm end member for guiding the wires to pass through the arm stem member and arm end member and is displaced toward the arm stem member by an amount corresponding to an extent of bending of the arm end member.
