PURPOSE:To provide rear wheel steering structure optimum for securing the stability of rear wheels in a traveling vehicle and enabling the realization of specified rear wheel steering in addition to holding a rear axle at a chassis frame while realizing specified spring operation. CONSTITUTION:A chassis frame B forming a vehicle body is disposed in the travel direction of a vehicle, and a rear axle A is disposed below this chassis frame B, in the cross direction of the chassis frame B so as to hold rear wheels T at both ends thereof. The rear axle A is supported at the chassis frame B through plate springs A and connected to the top part of an arm member 21 formed into angle shape with both ends thereof connected to the chassis frame B side while the center position C thereof being set as the rotational center. The rear axle A is further formed in such a way as to be oscillated horizontally around the center position C as the rotational center by the driving of one hydraulic cylinder 22 held onto the chassis frame B side. |
