PROBLEM TO BE SOLVED: To attain increase in power generation output by a power generator, by suppressing generation of noise and attain this, without generating the problem regarding its lifetime. SOLUTION: A generator 2 includes a first rotor 9 for supporting a magnet 8 and a second rotor 11 for supporting a power generation coil 10 facing the magnet 8. An engine 3 makes the first rotor 9 rotatively drive in one direction A and makes the second rotor 11 rotatively drive, in a direction B opposite to the one direction A. The first rotor 9 has a first rotating shaft 14, and a yoke 16 tapered and engaged, and supported with the free ends of this first rotating shaft 14, to support the magnet 8. The second rotor 11 has a second rotating shaft 19, and a core 21 tapered and engaged with the free ends of this second rotating shaft 19, to support the coil 10. The first, second rotors 9, 11 are disposed in the axial direction of the axial center 7 so that the free ends of the first rotating shaft 14 and the second rotating shaft 19 approach each other and face each other.
