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. 【課題】緊急避難時に、健常者の脚に力添えしてくれる脚の動作補助具を提供する。【解決手段】大腿部を介添えする揺動ロッド２と、揺動ロッド２の下方に連結されて下腿部を介添えする支持ロッド４と、支持ロッド４の上部に設けられて揺動ロッド２に対し、支持ロッド４を前後方向にのみ揺動自在に接続する接続手段３と、接続手段３の外側に設けられて揺動ロッド２に対し、曲げられた支持ロッド４に復元力を付与する板状の復帰バネ手段６とを備え、復帰バネ手段６は、少なくとも内周面が円弧形で外周面との間に支持ロッド４と連結し且つ支持ロッド４の長軸方向に対し略平行となる第一の切り込み部６ａと、接続手段３と連結し且つ第一の切り込み部６ａに対し略１８０?〜略２７０?の領域内に形成される第二の切り込み部６ｂとを設け、第一の切り込み部６ａに対し、近接させた第二の切り込み部６ｂに生じる復帰力を揺動ロッド２の復元力としたものである。【選択図】図１
