Claims

[Scope of Claim for Utility Model Registration] (1) A pump body inserted into the fuel tank through a pump insertion hole provided in the upper lid of the fuel tank, and a pump provided above the pump body and provided within the fuel tank. an upper cover that supports the main body and covers the pump insertion hole; a gasket that seals between the upper cover and the upper lid; and a screw hole provided in the upper cover through the gasket that connects the upper cover. a fixing screw that fixes the upper cover by screwing into a screw hole provided in the part;
In an in-tank fuel pump device comprising an anti-rust paint applied to the outer surface of the upper cover in order to prevent corrosion of the upper cover, the gasket has screw holes in the upper cover. An in-tank fuel pump device characterized in that a protruding pipe portion having an insertion hole inserted into the screw hole and into which the fixing screw is inserted is integrally molded at a corresponding position. (2) The in-tank according to claim 1, wherein a thick wall portion is formed at the tip of the protruding pipe portion to improve sealing performance between the screw hole of the upper cover and the fixing screw. type fuel pump device.
