An elliptical exercising device includes a rotating unit mounted on a support frame, and two link rods connected to the rotating unit such that intermediate segments of the link rods are moved reciprocatively in an elliptical path. A foot support is tiltably mounted on the intermediate segment. A suspending rail is moved with the foot support to be subjected to a gradually varying urging force resulting from movement of the intermediate segment and to be continuously urged to angularly move. A rail engaging rider slidably contacts the suspending rail to be urged by the urging force to angularly move upwards or downwards. An urging force counteracting mechanism is mounted pivotally on the support frame, and is coupled with the rail engaging rider so as to impart a force to counteract an x-axis force component of the urging force to thereby keep the suspending rail in a horizontal position.
