To provide a wheelchair that can easily be operated with either the right or left hand.SOLUTION: The wheelchair comprises: handrims; rotary shafts for transmitting rotational force generated by rotating the handrim on one side to the wheel on the opposite side by way of a drive mechanism; and wheel hubs for transmitting the rotational force generated by rotating the handrim on the one side to the wheel on the same side by way of the drive mechanism. The drive mechanism includes mobile shaft members, rotary shaft side discs, handrim side discs, and force application devices, each of which force application devices comprises a linking device for transmitting handrim movement to the mobile shaft member. When the handrim is moved, the linking device is press-contracted or press-expanded, causing the mobile shaft member to slide, so that an engaging part on the rotary shaft side disc and an engaging part on the handrim side disc selectively engage an engaging part on the rotary shaft and/or an engaging part on the wheel hub, transmitting the rotational force to the wheel on the intended side.SELECTED DRAWING: Figure 1

    【課題】左右いずれかの手で容易に操作できる車椅子を提供する。【解決手段】ハンドリムと、一方の側のハンドリムを回転させて生ずる回転力を駆動機構を介して反対側の車輪に伝達する回転軸と、一方の側のハンドリムを回転させて生ずる回転力を駆動機構を介して同じ側の車輪に伝達する車輪ハブを備え、駆動機構が、可動軸部材と、回転軸側ディスクと、ハンドリム側ディスクと、ハンドリムの移動を可動軸部材に伝達するリンク装置からなる加力装置を有し、ハンドリムを移動させると、リンク装置が押し縮められ又は押し広げられて可動軸部材を摺動させ、回転軸側ディスクの係合部及びハンドリム側ディスクの係合部が、回転軸の係合部及び/又は車輪ハブの係合部に選択的に係合して、回転力が所望の側の車輪に伝達されるように構成されている。【選択図】 図1
