A walking aid apparatus comprising a sitting member 1 which a user sit astride and leg links 2L and 2R each coupled to a connection 3 provided on the undersurface of the sitting member in such a way as to be free to swing in the forward/backward direction, which improves the stability of the sitting member. The connection 3 is adapted in such a way that a forward/backward swinging fulcrum of the leg links 2L and 2R is located above the sitting member. More specifically, the connection 3 is provided with an arc-shaped guide track 32 longitudinal in the forward/backward direction and having the center of curvature 3a above the sitting member 1, so that each of the leg links 2L and 2R swings along the guide track 32 in the forward/backward direction. If the leg links 2L and 2R are allowed to swing freely also in the lateral direction, preferably the lateral swinging fulcrum of the leg links 2L and 2R is located above the sitting member 1, too.
