VALVE STRUCTURE AND FUEL SUPPLY DEVICE

摘要

A valve structure includes a retention element, a first valve body, and a second valve body. The retention element is mounted to and is retained in a lower portion of a stored object. The stored object includes a pump device that pumps fuel from the fuel tank into the sub tank through a pumping passage that communicates an inside of the sub tank with an outside of the sub tank. The stored object is inserted from an upper portion of the sub tank and housed inside the sub tank. The first valve body is integrally formed with the retention element and extends from the retention element. The first valve body is located at a natural inlet open on the bottom portion of the sub tank. The second valve body is integrally formed with the retention element and extends from the retention element. The second valve body is located on the pumping passage.
