止弁のストツパー。[Claims for Utility Model Registration] (1) A valve body is fixed to a valve stem rotatably supported on both sides of the valve body in a fluid-tight or air-tight manner, and the valve body is opened by forward fluid pressure in the valve body. When the valve body rotates in the valve direction and in the valve closing direction due to reverse fluid pressure, the seat part of the valve body comes into contact with and separates from the seat part of the valve stem to open and close, and when the valve body to be opened collides with the valve box. In a check valve in which a stopper coated with an elastic material is provided protruding from each of the valve body side and the valve body side toward the other side for alleviating shock and setting the maximum opening degree of the valve body, at least one of the stoppers is connected to the valve body. A base material that protrudes from either the body side or the valve box side and has a recess formed on the surface facing the other side, and the surface of this base material is adhesively coated, and the part corresponding to the recess is thickened toward the other side. A stopper for a check valve, characterized in that it is formed of a protruding elastic material. (2) At least one part of the stopper facing the other side is attached to an arcuate concave tip surface of a base material protruding from either the valve body side or the valve box side, and is bonded to this tip surface. 2. The stopper for a check valve according to claim 1, wherein the cross-sectional shape of the elastic material is formed into a convex lens shape by the elastic material covering the distal end surface.
