Abstract
A fuel supply apparatus in which, even if a column support receiving region of a supporting member is broken, the breakage is prevented from reaching both surfaces of the supporting member. A flange member includes a circular plate-shaped flange body attached to a fuel tank, an inner sleeve into which a column support is inserted, and an outer sleeve located at an outer periphery of the inner sleeve that is integrally formed. A bottom portion of the inner sleeve extends farther on the opposite side of a sub tank than the flange body, and the column support for providing a connection between the sub tank and the flange member has one end press-inserted into the inner sleeve beyond the flange body to a point opposite the sub tank.

A fuel supply apparatus comprising:
- a pump case housed in a fuel tank;
- a fuel pump housed in the pump case, for drawing in and discharging fuel;
- a supporting member attached to an upper wall of the fuel tank;
- and
- a column support for providing a connection between the supporting member and the pump case,
- wherein the supporting member comprises:
- a plate-shaped flange body defining an inner sleeve;
- a bottom portion formed in the inner sleeve, the inner sleeve having on its pump-case side an opening and having an inner bottom surface which is located farther from the pump case than a portion of the supporting body, one end of the column support being inserted in the inner sleeve beyond the supporting body to the inner bottom surface;
- and
- an outer sleeve with a bottom formed in it, the outer sleeve having a bottom portion which is formed continuously with the bottom portion of the inner sleeve and having a tubular portion which is formed continuously with the supporting member, the bottom portion of the outer sleeve being located in a plane farther from the pump case than the bottom portion of the inner sleeve.
A fuel supply apparatus comprising:
- a pump case housed in a fuel tank;
- a fuel pump housed in the pump case, for drawing in and discharging fuel;
- a flange body defining an outer sleeve and an inner sleeve, wherein the flange body is attached to an upper wall of the fuel tank;
- and
- a bottom portion formed in the outer sleeve and a bottom portion formed in the inner sleeve, wherein the bottom portion of the outer sleeve and the bottom portion of the inner sleeve are parallel to each other and continuously formed with the flange body and each bottom portion closes an end portion of each respective sleeve at a location farthest from the pump case.
