Zusammenfassung:	A compensation rotational shaft 10 having a compensation weights 11 for cancelling out a free moment of a crank shaft 5 as a test piece is provided on a vibration cradle 1. The compensation rotational shaft 10 is rotated by a synchronous motor 9 other than a synchronous motor 8 for rotating the crank shaft 5. At this time, the synchronous motor 9 is rotated based on a reference signal detected by an optical sensor 18 (13, 14) in such a manner that the synchronous motor 9 is synchronously rotated with the rotation of the clank shaft. By these means a dynamic balance testing machine is provided with mechanical arrangements for canceling out a free moment of an asymmetrical crank shaft and capable of accurately measuring a rotating unbalance of the asymmetrical crank shaft.
