る逆止弁を設けたことを特徴とする脚体。A leg body in which an inner cylinder is slidably inserted into an outer cylinder, wherein either the outer cylinder or the inner cylinder is provided with a plurality of engaging parts, and the other is housed in the outer cylinder with the inner cylinder door. A lock pawl that engages with the engaging portion only in the direction of rotation is swingably supported, and a regulating body that restricts the engagement of the lock pawl with the engaging portion is reciprocatably attached. The forward movement of the regulating body releases the engagement of the lock pawl with the engaging part, and the backward movement causes the lock pawl to engage with the retaining part, while providing an air cushion inside the inner cylinder, The outer cylinder is provided with a piston that is slidably inserted into the air cushion chamber and compresses the air in the air cushion chamber when the inner cylinder is stored in the outer cylinder; A leg body comprising a check valve that opens the air cushion chamber to the outside when the air cushion chamber is pulled out from the outer cylinder.
