PROBLEM TO BE SOLVED: To provide a small size evaporated fuel-leak inspection device of a simple structure easy to manufacture having high inspection accuracy of evaporated fuel leak. SOLUTION: The evaporated fuel-leak inspection device is provided with a tank passage 140 communicating to the fuel tank, an atmospheric air passage 150 opened to atmospheric air, a pump passage decompressed by a pump, a first valve member 322 seated to and separating from a first valve seat 310, a second valve member 323 seated to and separating from a second valve seat 311, and a support member 324 supporting the first valve member 322 and the second valve member 323. In this case, a reference orifice 510 of which one end side communicates to a tank passage 140 and the atmospheric air passage 150 under a condition where the second valve member 323 is seated on the second valve seat 322 is formed on the support member 324 eccentrically to a center axis line O of a shaft member 321.
