Abstract

PROBLEM TO BE SOLVED: To reduce stress applied to the joint of a leg, a hip joint and muscles by providing a front movable roller freely rotatably pivoted by the end part of the front side of an orbit forming body and a rear movable roller freely rotatably pivoted by the end part of the rear side of the orbit forming body, and mounting a movable belt to these movable rollers. SOLUTION: In the case that a user who grasps upper rods 5, 5 and stands in a center of the movable belt 9 freely rotatably mounted to the front movable roller 7 and the rear movable roller 8, his/her stepped-out left leg lands on the front side of the belt 9 and his/her right leg to kick out kicks the rear side of the belt 9. Since this belt 9 is attracted to the upper surface of the orbit forming body 6 by magnetic force, it passes through the same orbit as the body 6 on the upper surface side of the body 6, namely the same orbit as a curved locus similar to the locus of the naturally swinging arch of the leg obtained by linking human hip joint, knee joint and ankle joint with each other.
