<p>PROBLEM TO BE SOLVED: To reduce the torsional vibration of a crank shaft due to the load of a dynamo or a motor and reduce a stress. SOLUTION: This device is a dynamo or a motor which is provided in a part of an engine and provided with a magnetic force generating member provided in the moving part of the engine and a stator coil 17 provided in an engine case 1 and disposed close to the moving route of the moving part to bring about an interaction between the magnetic force generating member and the stator coil 17. The magnetic force generating member is, for instance, a permanent magnet 15, and the moving part is a piston 7, a connecting rod 13, a crank shaft 11 or the like.</p> |
