In a vibration generating machine having two rotary shafts provided with eccentric spindles disposed parallel to each other, motors Ma, Mb are disposed so as to reduce the capacity or power consumption of the motors required in a vibration generating machine having two rotary shafts provided with eccentric spindles disposed parallel to each other, and to drive the two rotary shafts 31a, 31 b independently, and a rotary drive control mechanism is constituted so that either one of the two rotary shafts 31a, 31b may be started upon start, while the other rotary shaft may started after the rotary drive state of this rotary shaft is transferred to a stationary state. |
