PURPOSE:To reduce the weight of the captioned valve and prevent the position of a valve seat from changing when an external force is applied to an outlet pipe by integrally forming the holding body portion of the valve seat and the outlet pipe with a thin-wall pipe. CONSTITUTION:An outlet pipe 14 forming an outlet passage 7 is integrally formed with a holding body portion 14a holding a valve seat 8, with a thin-wall pipe. The casing side of the outlet pipe 14 has a bellows type bend portion 14b. The outlet pipe 14 and the holding body portion 14a of the valve seat 8 which are integrally formed with a thin wall pipe enable a light-weight structure. Also, at the time of the piping operation of a fuel hose, particularly, at the time of removing the fuel hose for change, a force of bending the outlet pipe 14 may be applied. In such a case, the bellows type bend portion 14b is deformed, without deforming up to the holding body portion 14b of the valve seat 8 in the casing. |
