Zusammenfassung:A fuel passage structure of a fuel supply device is configured to supply fuel from a fuel tank to an internal combustion engine. The fuel passage structure includes a passage-forming member that forms a fuel passage and a check valve. The fuel passage includes a vertical passage extending in a vertical direction and a lateral passage extending in a horizontal direction. The check valve is disposed at an intersection of the vertical passage and the lateral passage. The check valve includes a valve body configured to close under its own weight. The valve body is movably arranged within the vertical passage in the vertical direction. The check valve is provided with a restriction member which restricts movement of the valve body into the lateral passage, while at the same time the restriction member does not disturb the forward flow of the pressurized fuel.
