PURPOSE:To prevent an excessive stress from acting on a piping even at the time of the vibration of a vehicle body by providing a flexible hose in said steering piping for connecting a hydraulic pump to a rear wheel steering device. CONSTITUTION:A rear wheel control valve 21 is fed with an oil pressure from a hydraulic pump 10 via steering piping. The steering piping consists of a first steering piping 14a, a second steering piping 15a, a third steering piping 16a, a flexible first hose piping 17a which connects the first and second steering pipes, and a flexible second hose piping 18a which connects the second and third steering pipings. Since the first and second hose pipings for connecting each steering piping are of flexible hoses, it can be prevented that excessive stress is generated in each steering piping at the time of vibrating. |
