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.
