Abstract

See full text

An evaporated fuel processing device includes a liquid level surface detection valve that detects a full-tank liquid level surface when refueling, and closes a canister communication hole; a fuel shutoff valve to close an evaporation hole when a liquid level surface becomes higher than the full-tank liquid level surface; and an outlet port communicating with a canister. A first communication path and a second communication path are formed in a folded back shape folded back at a first valve seat upper part in plan view. The first communication path enables communication between the first valve seat upper part and a second valve seat upper part, and the second communication path enables communication between the first valve seat upper part and the outlet port. This constitution reduces fuel liquid leakage from the outlet port.
