EVAPORATED FUEL PROCESSING DEVICE

摘要

An evaporated fuel processing device (1) includes the following: a liquid level detection valve (2) that detects a full-tank liquid level when refueling, and closes a canister through hole (4); a fuel shutoff valve (3) that closes an evaporation hole (6) when the liquid level is higher than the full-tank liquid level; and an outlet port (9) that communicates to a canister. In plan view, a first communication path (21) that enables communication between a second valve seat upper part (12) and a first valve seat upper part (11), and a second communication path (22) that enables communication between the first valve seat upper part (11) and the outlet port (9) are formed in a folded back shape at the first valve seat upper part (11). This configuration reduces fuel leakage from the outlet port (9).
