Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rocker valve which is operated simply by pressure medium, has a simple structure while saving an arrangement space, is used for variable purposes, secures maximum operation certainty, accuracy, and short changeover time by improving the conventional rocker valve having a pneumatic pilot control device in which one leg of a rocker inserted into a casing is subjected to load application by pilot pressure through a pilot connection part, the rocker is airtightly blocked at a one terminal position, and released at the other terminal position. SOLUTION: A seal member 2 is arranged between an edge of a rocker 1 and an inner wall of a casing G at least one side of the rocker 1 having operation connection portions A1, A2. A chamber having at least two connection portions is formed at one side of the rocker related to a shaft and a rocker flat surface 1 by the seal member 2. The chamber is separated from the rocker surface at the other side of the rocker by means of at least another connection portion.
