PROBLEM TO BE SOLVED: To provide the safe rim structure of a wheel for a wheelchair, that facilitates replacement of hand rims without performing an operation to attach/detach a tire, a tire tube, and a rim band, etc., to/from the rim of a wheel for a wheelchair.SOLUTION: The rim structure 30 of a wheel 3 has a nut member 12 including: a flat plate 12a a fitting projection 12b and a male screw 12c formed to penetrate the flat plate 12a and the fitting projection 12b. Fixing is performed by making the fitting projection 12b of the nut member 12 be inserted into a through-hole 5e arranged in the rim groove 5a of the rim 5 from the outer peripheral surface side of the rim 5 and performing caulking, etc. Besides, a bolt 13 inserted into the attachment hole 10c of a stay 10b is screwed onto the male screw 12c of the nut member 12 from the inner peripheral surface side of the hand rim 10.COPYRIGHT: (C)2013,JPO&INPIT【課題】車いすの車輪のリムからタイヤやタイヤチューブ、リムバンド等を着脱する操作を行なうことなく容易にハンドリムの交換が可能で、しかも安全な車いす用車輪のリム構造を提供する。【解決手段】車輪3のリム構造30は、平板部12aと嵌合突起部12bとを有し、該平板部12aと該嵌合突起部12bとを貫くように形成された雌ねじ部12cを有するナット部材12を備えている。リム5のリム溝部5aに設けられた貫通孔5eに、リム5の外周面側から該ナット部材12の嵌合突起部12bが挿通された上でかしめ加工等されることで固定され、さらに該ナット部材12の雌ねじ部12cに、前記ハンドリム10の内周面側から前記ステー10bの取付孔10cに挿通されたボルト13が螺合される。【選択図】図3
