PURPOSE: A supporting structure of a vibration type spring is provided to prevent a part from breakage by preventing a piston and a cylinder from wearing and to increase pressing efficiency. CONSTITUTION: The supporting structure of a vibration type spring comprises:a piston(8) moving rotatively in a shaft direction by delivering the driving power of a motor; a first spring(12') in which one side is fixed on one side of the piston and the other side is supported; the second spring in which one side is fixed on the other side of the piston and the other side is supported; the step of supporting elastically the movement of the piston by the shaft direction shrinking and relaxation of the first and second spring.
