Abstract: A fuel supply device includes a fuel pump and a filter case that houses a fuel filter, a fuel pumped by the fuel pump from inside a fuel tank is filtered by the fuel filter and supplied from inside the filter case toward an internal combustion engine, and the filter case includes a case body having a closed bottom shape that forms a housing chamber of the fuel filter, a case cap that covers an aperture of the case body by being joined to the case body, and a residual pressure retention valve that, when the fuel pump is stopped, retains a pressure of the fuel supplied from inside the filter case toward the internal combustion engine, the residual pressure retention valve being disposed at a joint boundary of the case body and the case cap.

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.
