PROBLEM TO BE SOLVED: To facilitate avoidance of resonance between an engine and a generator without upsizing of the generator. SOLUTION: The generator 2, the engine 1, and a control board 6 are installed on a rubber vibration isolator 3 on a base 4, and the generator 2 and the engine 1 are directly connected to each other. On the underside of a mounting base 2a below the generator 2, a mass member 16 is mounted using bolts and nuts 16a, which is capable of changing the natural frequency of the generator 2 by changing shapes, quantity or material. The natural frequency of the generator 2 is set up so as not to resonate with the vibration during combustion of the engine 1 by adjusting the mass of the mass member 16. COPYRIGHT: (C)2006,JPO&NCIPI
