To provide a bicycle with a wheelchair, capable of easily coupling the bicycle and the wheelchair without largely remodeling the bicycle and the wheelchair, also capable of being steered with small force, and capable of stably traveling.SOLUTION: A coupling auxiliary tool for a bicycle with a wheelchair, for coupling the wheelchair and the bicycle from which a front wheel is removed, includes: a wheelchair-side fixing part laid between right and left main wheel shafts of the wheelchair; a bicycle-side fixing part to which a front fork of the bicycle is coupled; and a joint part that rotatably couples the bicycle-side fixing part and the wheelchair-side fixing part. In a state in which the joint part is inclined forward with respect to the wheelchair-side fixing part, the joint part couples the bicycle-side fixing part, thereby setting a caster angle between a steering shaft and a main wheel to be minus; therefore, the steering wheel can be lightly turned, thus obtaining stable steering performance.SELECTED DRAWING: Figure 1

    【課題】自転車と車椅子を大きく改造することなく容易に結合することできるとともに、小さな力で操舵ができ安定した走行が可能な車椅子付き自転車を提供すること。【解決手段】車椅子と前輪を外した自転車とを結合するための車椅子付き自転車の結合補助具は、車椅子の左右の主輪軸間に架け渡した車椅子側固定部と、自転車のフロントフォークを連結した自転車側固定部と、該自転車側固定部と前記車椅子側固定部とを回転自在に結合するジョイント部とからなり、前記ジョイント部が前記車椅子側固定部に対して前傾した状態で自転車側固定部を結合することで、操舵軸と主輪とのキャスター角がマイナスになるようにしたので、ハンドルを軽く回すことができて、安定した操舵性を得ることができる。【選択図】図1
