度をもつて傾斜させた燃料流出防止弁。 A valve body is loosely fitted into a body having an evaporated fuel inlet and an outlet, and a spherical seal formed on the upper end surface of the valve body by the buoyancy of the fuel flowing into the body is formed at the outlet. In the fuel outflow prevention valve that comes into contact with a conical seat surface formed at an opening end in the body to cut off communication between the inlet and the outlet, the fuel outflow prevention valve has the body divided into an upper chamber and a lower chamber; A partition portion having a communication hole for the chamber is provided, and two symmetrical notches into which the partition portion is inserted are provided in the valve body, and the upper chamber is moved in one direction on the partition portion within the valve body. A movable steel ball is fitted loosely,
A plate valve body, which is inserted into the communication hole and has a protrusion that can protrude into the upper chamber, is integrally fixed to the lower end of the valve body located in the lower chamber, and furthermore, the upper surface of the partition portion is connected to the communication hole. A fuel outflow prevention valve tilted at a predetermined angle toward the hole.
