PROBLEM TO BE SOLVED: To provide an auxiliary wheel capable of stably executing switching of forward/rearward movement or direction change of hard cornering while balancing a vehicle itself having no steering device and loaded with a heavy weight by smoothly performing a direction change against a traveling direction with two wheels interlocking with each other and to provide a cart having such an auxiliary wheel.SOLUTION: The auxiliary wheel includes: an axle; two wheels journaled to each other to independently rotate around the axle normally and reversely; a moving member for supporting the axle; and a fixing member for fixing on a vehicle frame. The moving member includes a fixing member connection part rotatably mounted on the fixing member at one end and a rod-like part connecting between the fixing member connection part and the axle for supporting, and an extension line of a steering shaft of the fixing member connection part and the axle make no intersection.SELECTED DRAWING: Figure 1

    【課題】本発明は、操舵装置を備えない車両に関して、二輪が連動して進行方向に対してスムーズに方向転換を行うことにより、重量物を積載した車両自体がバランスを保ちながら安定して前後進の切換又は小回りの方向転換が可能な補助輪を提供することを目的とする。さらに、前記補助輪を備えた運搬車を提供することを目的とする。【解決手段】上記課題を解決するため、本発明の補助輪は、車軸と、車軸の周りを正逆自在に独立して回転する軸着された二個の車輪と、前記車軸を支持する可動部材と、車両フレームに固定するための固定部材と、を備え、前記可動部材が、一方端において前記固定部材に対して回転可能に取り付ける固定部材連結部と、前記固定部材連結部と車軸との間を連結して支持する棒状部と、を有し、前記固定部材連結部の転舵軸の延長線と前記車軸とが交差しないこと、を特徴とする。【選択図】 図1
