Abstract

A fuel cutoff valve comprises a casing main body with a connecting hole and a valve chamber, a cover forming the tube member, and the float housed in the valve chamber. The valve comprises, above the casing main body, the liquid closure member forming the retaining chamber for temporarily retaining liquid fuel flown out of the connecting hole and the partition member formed in plurality in a ridge form on the upper surface of the upper wall within the retaining chamber. Each partition member is arranged radially so as to be connected to the liquid closure member from the near center of the connecting hole, and configured in such a way that the retaining chamber is divided into multiple divided chambers.
