Abstract
A fuel cutoff valve comprises a casing, a cover having a cover supporting part for supporting an upper part of the casing, an O-ring disposed on an outer periphery of the casing, and a seal holding member. The seal holding part is constituted by a member made of a material having a high degree of shape stability, such as a polyamide, into which glass fibers are added. Further, the seal holding part is thermally welded to a welding end of a cover inner layer made of a modified polyamide.
