PROBLEM TO BE SOLVED: To provide a stable walking posture and improve the alternating walk by connecting the inside parts of the femoral region with an inside part crotch joint, arranging the rotating center of the inside crotch joint in the position substantially conformed to the rotating center of a crotch joint fitting, and moving the inside crotch joint so that the motion of lateral lower extremity struts forms alternating walks. SOLUTION: In a walk auxiliary apparatus 1, lower extremity struts 5L, 5R for supporting the femoral region and lower extremity parts are pivotally fixed to a pelvis trunk apparatus 2 through lateral crotch joint fittings 3L, 3R attached on both sides in such a manner as to be longitudinally rockable. An inside crotch fittings 30 is continued to the lower extremity struts 5L, 5R in the inside parts of the femur parts on each lateral side, and the rotating center of the inside crotch joint 30 is arranged in a position substantially conformed to the rotating center of the crotch joint fittings 3L, 3R, and the lateral lower extremity struts 5L, 5R are moved with a reverse phase so that their movements are alternated. When the lower extremity struts 5L, 5R are alternately moved, a walking force is alternately transmitted with the crotch joint fitting shaft as the center to provide a stable walking state. |
