To propose a hand rim for a wheelchair in which the joint strength with the wheel of the wheelchair can be improved, and the wheelchair can stably be used over a long term, and its manufacturing method.SOLUTION: A hand rim for a wheelchair includes a rim body 2 made by fiber reinforced plastic, and multiple mounting members 11 disposed at intervals in the circumferential direction of the rim body 2. The mounting member 11 includes an embedded part 13 embedded between layers of the reinforcing fibers of the fiber reinforced plastic for configuring the rim body 2, and a protrusion 12 protruded from the rim body 2. The hand rim 1 having such a configuration is improved in the joint strength between the rim body 2 and the mounting member 11. Also, as a manufacturing method of such hand rim 1, there are included a forming step of laminating the reinforcing fibers and a curing step of curing matrix resin. In the forming step, the embedded part 13 of the mounting member 11 is arranged between the layers of the reinforcing fibers.SELECTED DRAWING: Figure 2 【課題】車いすのホイールとの接合強度を向上でき、該車いすを長期に亘って安定して使用し得る車いす用のハンドルリムと、その製造方法とを提案する。【解決手段】繊維強化プラスチック製のリム本体２と該リム本体２の周方向に間隔をおいて複数配設された取付部材１１とを備え、取付部材１１は、リム本体２を構成する繊維強化プラスチックの強化繊維の層間に埋設された埋設部１３と、該リム本体２から突設された突設部１２とを備えたものである。かかる構成のハンドリム１は、リム本体２と取付部材１１との接合強度が向上する。また、こうしたハンドリム１の製造方法としては、強化繊維を積層する形成工程と、マトリクス樹脂を硬化する硬化工程とを備え、該形成工程で、該強化繊維の層間に前記取付部材１１の埋設部１３を配置させる。【選択図】図２
