Claims (1)

[Claims for Utility Model Registration] (1) A treatment for directly connecting a first load end face disposed facing the base and a second load end face opposite to the first load end face to the lower surface of the vehicle body or a member fixed thereto. a double-acting hydraulic cylinder with a shortened axial length including a tool; a high-speed electromagnetic switching valve that supplies pressure oil to the hydraulic cylinder; a high-speed electromagnetic switching valve control device; and a feedback signal input to the control device. A vibration device characterized by having a position sensor. (2) The hydraulic cylinder has a medium-diameter outer peripheral surface, a large-diameter outer peripheral surface, and a contact surface connected to the second load end surface, and a small-diameter inner peripheral surface inward of the medium-diameter and/or large-diameter outer peripheral surface. A first piston member having a medium-diameter inner circumferential portion, a large-diameter inner circumferential surface, an abutted surface, and the first load end surface that accommodate the first piston member in a nested manner are successively connected to each other, and a second piston member having a small diameter outer circumferential surface that is in sliding contact with the small diameter inner circumferential surface;
2. The vibration device according to claim 1, wherein said high-speed electromagnetic switching valve is arranged on an outer surface of said second piston member. (3) The vibration device according to claim 2, wherein the position sensor is attached to a sensor support member connected in parallel to the first piston member in the axial direction. (4) The vibration device according to claim 1, wherein the vibration device is attached via a bracket to a pair of hydraulic jack cylinders of a hydraulic jack that adjusts the height of the lower surface of the vehicle body or a member fixed thereto relative to a base.
