Abstract: A walking assistance device includes: a waist attachment portion attached to a waist; a right knee attachment portion attached to a right knee; a left knee attachment portion attached to a left knee; and a wire that extends from the right knee attachment portion along a front surface of a right thigh, passes through the waist attachment portion, and extends along a front surface of a left thigh to reach the left knee attachment portion. The wire assists a motion of swinging the left thigh forward when the right thigh is kicked backward, and assists a motion of swinging the right thigh forward when the left thigh is kicked backward.

Abstract: The walking assistance device includes: a waist attachment portion attached to a waist; a left knee attachment portion attached to a left knee; and a stretchable left leg wire that connects the waist attachment portion and the left knee attachment portion and that extends along a front surface of a thigh. A motion of swinging the thigh forward is assisted by an elastic restoring force of the left leg wire. The waist attachment portion includes a wire guide extending along an outer periphery of the waist. The left leg wire extends from the left knee attachment portion toward the waist attachment portion, is guided by the wire guide and extends along the wire guide, and is selectively anchored to at least two or more anchoring portions separated from each other in a longitudinal direction of the wire guide.
