Abstract
A fuel cutoff valve and a method for making the same having a simpler mounting operation and excellent sealing properties are disclosed. The fuel cutoff valve includes a cover, a casing made of a different resin than the cover wherein the casing includes a valve chest and a valve body accommodated in the valve chest. The casing is used as an insert member having a plurality of sealing ribs projecting substantially vertically towards the cover, and a stopper formation forming a substantially horizontal step at substantially right angles to the sealing ribs, and the cover is integrally formed therewith so as to enclose the sealing ribs and stopper formation of the casing. The fuel cutoff valve may also be constructed such that the cover is used as the insert member as opposed to the casing. The stopper formation can be a rib, a recess or a through-hole.
