Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a rod-less cylinder equipped with two pistons, which is provided with a means capable of changing a distance between the pistons to any distance at any time.

SOLUTION: Both ends of a cylinder are blocked by an end cap. In the inside of the cylinder, two pistons reciprocated in the cylinder by fluid pressure are disposed. A space surrounded by the two pistons and the cylinder inner wall and a port for supplying and exhausting air provided on the end cap are communicated and coupled through a coiling tube disposed in the cylinder.
