Abstract
A support shaft connects between a flange and a pump unit. An intermediate member, which connects between the support shaft and pump unit, enables a relative positional change between the support shaft and the pump unit in an axial direction of the support shaft. The intermediate member limits a relative positional change between the support shaft and the pump unit in a circumferential direction of the support shaft. A resilient member is received in the support shaft and exerts a restoring force in an axial direction of the support shaft to urge the pump unit, which is movable relative to the support shaft in the axial direction, toward a bottom portion of the fuel tank.

A fuel supply apparatus comprising:
- a flange that is configured to be installed to a fuel tank;
- a pump unit that is configured to be installed in an inside of the fuel tank to pump fuel received in the inside of the fuel tank to an outside of the fuel tank;
- a support shaft that is configured into a tubular body and connects between the flange and the pump unit;
- and
