PURPOSE:To improve accuracy in adjusting vibration by adjusting the vibration of a vibrating body based on a vibration value which is obtained by amplifying a vibration value. CONSTITUTION:A rotary body 7 is rotated by means of a driving motor 6, thereby, the vibration value of the rotary body 7, having unbalance, is transmitted to a bearing box 8, being slightly damped down. The displacement, by vibration, of the bearing box 8 is transduced into an electrical quantity by means of a detector, and inputted into a data recorder 10. The vibration value inputted into the data recorder 10 is amplified there, regenerated, and inputted into a vibroscope 9. And, based on an obtained vibration value, the compressed quantity of an exciting elastic body 12, which is interposed between the bearing box 8 and a floor surface, is adjusted by means of an adjusting bolt 14. |
