PURPOSE:To provide a tank which can be easily mounted on and removed from a propulsion machinery body so as to enable to refuel the tank at a place apart from the propulsion machinery body, and to prevent the leakage of fluid from the suction tube while the tank is removed. CONSTITUTION:A fluid outlet member 31 and a tank junction member 32 of a suction tube 20 are mounted removably on the oil tank 19 and on the corresponding bottom of the tank case 26, respectively. The fluid outlet member 31 is provided with a ball valve 34 which is spring supported by a compression spring 33 in the closing direction. The tank junction member 32 is provided with a circular valve 36 which is spring supported by a compression spring 35 in the closing direction. The circular valve 36 serves as a check valve which can prevent the lubricating oil from outflowing from the oil tank 19 or leaking from the suction tube 20 while the oil tank 19 is removed from the tank case. |
