PURPOSE:To enable the captioned unit to be installed stably by providing the center of gravity of the unit without any fuel filled and the center of gravity of a fuel tank filled with fuel, respectively, inside a triangular cone of a triangular bottom surface linking together the three feet portions supporting the unit at three points. CONSTITUTION:A unit 1 is composed of an engine 10, a generator 20 driven by the engine 10 and a fuel tank 30 provided above the engine 10 and the generator 20. Ground feet portions 2-4 are to be provided on the respective three places enclosing the intersections of a perpendicular brought down from a center of gravity G1 of the unit 1 in the state of an empty fuel tank and the bottom surface of the unit 1. The center of gravity G1 of the unit 1 in the state of empty fuel is to be positioned inside a triangular cone tilting with a stable angle of elevation toward the triangle linking each feet portion 2-4 together. A center of gravity G2 of the fuel itself is to be positioned in a location higher than the center of gravity G1 of the unit 1 in a state of empty fuel together with a fuel tank 30 which is to be provided so that the center of gravity G3 of the unit 1 in the fuel filled state will be positioned inside the triangular cone. |
