Claims

[Scope of utility model registration request]

A hydraulic bypass device with pressure valves and return valves is installed between the power steering pump and the steering gear box, and between the power steering reservoir tank and the steering gear box, and the front left and right cylinders and rear left and right cylinders are installed in the rocker part of the vehicle body. a vehicle body lifting/lowering piston device, each of which is provided with a piston in each of said cylinders and forming a seat for raising and lowering a vehicle body; A hydraulic path switching device formed by a pressure switch and a return switch connected to the hydraulic path switching device, a main switch that opens and closes the hydraulic bypass device, and a lift switch that opens and closes the hydraulic path switching device. A lifting device for a vehicle body, characterized in that the changeover switch device is selectively opened and closed to send the hydraulic pressure of the power steering pump to the hydraulic path switching device, and the vehicle body lifting piston device is actuated to raise and lower the vehicle body.
