Abstract
Upper arms are fixed to drive shafts of a pair of drive sources at or near respective left and right hip joints. The upper arms are coupled to an upper body trunk harness by first passive rotary shafts via third passive rotary shafts, and are mounted to a lower body trunk harness by a mounting device. Lower arms are fixed to drive source bodies, and are coupled to thigh harnesses by second passive rotary shafts via fourth passive rotary shafts. The first and second passive rotary shafts and third and fourth passive rotary shafts are angularly displaceable about axial lines in a lateral direction of the wearer and axial lines in an anteroposterior direction of the wearer, respectively. An acceleration/angular speed sensor fixed to the lower body trunk harness detects an acceleration of the body trunk in a vertical direction by landing of a foot.
