<p>PROBLEM TO BE SOLVED: To provide an aid for leg motion, assisting healthy person's legs in emergency evacuation.SOLUTION: An aid for leg motion includes: an oscillation rod 2 assisting the femoral region; a support rod 4 connected to the lower portion of the oscillation rod 2 and assisting the cruris; connection means 3 provided above the support rod 4, and swingably connecting the support rod 4 to the oscillation rod 2 only in a front/back direction; and tabular return spring means 6 provided outside the connection means 3 and giving a restoring force to the support rod 4 bent to the oscillation rod 2. The return spring means 6 is provided with a first notch 6a whose at least inner peripheral surface has a circular arc shape, and which is connected to the support rod 4 between itself and the outer peripheral surface and is nearly parallel to the long axis direction of the support rod 4, and a second notch 6b which is connected to the connection means 3, and formed in an area with almost 180° to almost 270° to the first notch 6a, and a return force occurring in the second notch 6b adjacent to the first notch 6a becomes a restoring force.</p> |
