PROBLEM TO BE SOLVED: To provide a vibrator for vibrating a movable body either vertically or horizontally. SOLUTION: This vibrator is provided with the vibrating table 3 supported on a frame 1 with a vibration-proof rubber 2, the rotating shafts 4A to 4D provided in parallel with the table 3 and each furnished with an unbalancing weight, a motor 6 for outputting a driving force to rotate the shafts 4A to 4D, a transmission mechanism 7 provided with a rotating direction changing mechanism for transmitting the driving force of the motor 6 so that the adjacent rotating shafts 4A to 4D are rotated respectively in the opposite direction and a weight position changing mechanism provided on the route of the transmission mechanism 7 relatively rotating the unbalancing weights provided to the shafts 4A to 4D around the axial centers of the shafts 4A to 4D and separately displacing the weights. |
