PROBLEM TO BE SOLVED: To provide a fuel outflow preventive valve capable of being easily installed on a resin made fuel tank by securing a sealing property. SOLUTION: A mounting part is molded of resin having roughly the same thermal expansion coefficient as resin molding a fuel tank T on a fuel outflow preventive valve to fix a flange 15 around an opening (h) provided on the resin made fuel tank T by securing a sealing property by molding a mounting part 11 having the flange 15 of resin on a valve cylinder 1 molded of resin so as to be integrated, and the valve cylinder 1, a valve seat ring 21 arranged in the inside of the valve cylinder 1, a lower cover 51 to function as a filter which is installed on the valve cylinder 1 in such a way as to close a lower end and a float 31 arranged in the valve cylinder 1 on which the lower cover 51 is installed are made of polyacetal resin. |
