The vibration device according to the invention includes a compensating device influenced by compensating masses for exciting forces caused by the vibrationary movement, the compensating masses respectively being arranged as partial masses on a hollow shaft, being coaxial with respect to one another, and including a displacing rod in their center by means of which the partial masses of the compensating weights can be displaced in the same manner as the eccentric determining the vibrational movement.
