新案登録請求の範囲第１項に記載の弁構造。[Claims for Utility Model Registration] (1) A tapered valve seat provided around the opening end of a fluid passage, a valve element that moves forward and backward with respect to the opening surface of the fluid passage, and a valve seat provided around the valve element. The O-ring is attached to a concave groove formed around the valve body, and connects to the valve seat to close the fluid passage when the valve body is in the closed position. This valve structure has a width that allows the O-ring to move in the same direction as the valve seat, and a tapered surface that slopes in the same direction as the valve seat on the bottom surface of the groove. (2) The valve structure according to claim 1, wherein the inclination angle A of the valve seat and the angle B of the tapered surface of the valve body have a relationship of A=B or A<B.
