<p>PROBLEM TO BE SOLVED: To reduce an initial oil feed quantity and an invalid residual quantity. SOLUTION: A channel-shaped throat part 11 is provided in the bottom of a sub-tank 1. The throat part 11, which is a channel for feeding fuel in a fuel tank to the sub-tank 1 by a jet pump, has one end opened outside the sub-tank 1 as a suction port 11a and the other end opened inside the sub-tank as a feed port 11b. The throat part 11 is inclinedly provided so as to become gradually higher from the suction port 11a towards the feed port 11b. The sub-tank 1 is provided with a check valve 12 opening/closing the feed port 11b of the throat part 11 in its inside. The check valve 12, which prevents the fuel in the sub-tank 1 from flowing outside the sub-tank via the throat part 11 is constituted into an approximately perpendicular state when the valve is closed (a state where the check valve 12 closes the feed port 11b).</p> |
