The purpose of the present invention is to enable required electric-motor capacity and power consumption to be reduced in a vibration generation device in which two rotational shafts provided with eccentric weights are arranged in parallel. Accordingly, a rotation drive control mechanism is configured such that: electric motors (Ma, Mb) are provided such that two rotational shafts (31a, 31b) are independently driven; and, during start up, one of the two rotational shafts (31a, 31b) is started, and, after a rotation drive state of this rotational shaft has transitioned into a constant state, the other rotational shaft is started. |
