Summary:PURPOSE:To lessen vibration by a compact constitution in which plural vibro- rotators are turned synchronously in each cylinder and act on the inner walls of cylinders of eccentric rollers to generate high-frequency vibration in the direction of the right angle to the drive shaft. CONSTITUTION:When rotators 7 are turned, eccentric rollers 9 are turned in contact with the inner surface of a cylinder 4 by centrifugal forces. The rotary shaft of the roller 9 is supported slidably in the direction of right angle to the drive shaft 60 of the rotator 7, and the shaft 60 is driven by a drive motor 110. A gear to turn two rotators synchronously in the opposite directions with engagement of a gear 13 fixed to the drive shaft 6 is fixed to the drive shaft 60 by insertion. The weight of the vibrator can thus be designed to a necessarily minimized extent, and the vibrating power can be economized. The vibrating load to the driver can also be greatly reduced.
