<p><P>PROBLEM TO BE SOLVED: To avoid sticking of a fluororesin coating film of a valve element to a metal sheet when an amount of plasticizer from a fuel hose is large, and to exert excellent durability when elution of the plasticizer is reduced after the continuous operation. <P>SOLUTION: In an injector valve element 1 of an injector for gaseous fuel, a close contact member in which a surface of a base material 2 made of rubber material includes fluororesin coating film 4, is disposed to a working face. The fluororesin coating film 4 is constituted of: a first fluororesin coating film 41 coated on the surface of the base material 2 and excellent in durability; and a second fluororesin coating film 42 applied on the first fluororesin coating film 41 and excellent in separation property. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
