PROBLEM TO BE SOLVED: To ensure safety of a traveling state of a vehicle having a special travel mode such as a mode of steering left and right wheels in left and right opposite directions.SOLUTION: A steering device comprises a steering mechanism 20 capable of steering left and right wheels in left and right opposite directions, and a plurality of lock mechanisms 50 for preventing actuation of the steering mechanism 20 by inputs from the wheels W. Even when a failure occurs to one of the lock mechanisms 50, a lock function is exerted by the other lock mechanism 50. Thus, the left and right wheels W are prevented from being steered unexpectedly by resistance received by the wheels W from a road surface, thereby ensuring a stable traveling state.SELECTED DRAWING: Figure 5
【課題】左右の車輪を左右反対方向に転舵する等の特殊走行モードを備えた車両の走行状態の安定性を確保すること。【解決手段】左右の車輪wを左右逆方向に転舵可能な転舵機構20と、車輪wからの入力によって、転舵機構20が作動するのを防止する複数のロック機構50と、を備えたステアリング装置を構成する。万が一、一つのロック機構50が失陥した場合においても、他のロック機構50によるロック機能が発揮され、車輪wが路面から受ける抵抗によって、不用意に左右の車輪wが転舵するのを防止し、安定した走行状態を確保する。【選択図】図5
