SOLE OF SHOE FOR LOWER LIMB OUTFIT

PURPOSE:To provide a sole of shoe capable of changing the thickness easily and lighten the burden on a user caused by increase in the weight by constituting it by a method where the upper and lower parts of a hole of shoe are connected by means of a link mechanism, expandable driving is carried out, through a drive wire, by an actuator arranged at a remote place on a walking assisting device. CONSTITUTION:When a leg of a user is in an idle condition an actuator is not actuated, and a spring 41 presses an upper link member 7 to the outside under a condition connecting links 6a, 6b are in a free condition, so that the links 6a, 6b are bent to the outside. When the leg is a support leg, the actuator is operated, an inner wire 27 is pulled, one rotating shaft 11 of the connection link 6a is pulled and raised, and at the same time, the other link 6b is pushed to the inside and raised by means of reaction force of an outer cable 26, so that the thickness of the sole of shoe 1 is increased. When the force of a piston is released, the front and rear link members are expanded to the outside by means of the spring 41, and thereby the sole of shoe becomes thin.
