<p>PROBLEM TO BE SOLVED: To provide a configuration which increases eccentric moment without increasing a dimension of a vibration generator.SOLUTION: A vibration generator (1) having a stationery eccentric weight (11) and a movable eccentric weight (12) which keep a predetermined phase difference and are rotationally driven around a rotary shaft (O) and a phase regulator (17) for regulating a phase difference between the two eccentric weights (11) and (12), in which each of the two eccentric weights (11) and (12) has one or more pin members which are embedded therein, and the pin members are disposed in a direction same as a direction of the rotary shaft and comprises a material having a specific gravity larger than that of a material which forms the eccentric weights.</p> |
