PROBLEM TO BE SOLVED: To provide an auxiliary brake that enables a wheelchair to be carried by releasing brake force and rotating the tires, and to provide a wheelchair equipped with this auxiliary brake.SOLUTION: The auxiliary brake includes: a swing arm member 12 that is provided freely approaching to and separating from the lower face of a sheet-like seat part 2 a cam member that postures for biting the periphery of a tire to prevent the tire from rotating when a user begins to stand up from the sheet-like seat part 2, and that postures for receding from the periphery of the tire to allow the tire to rotate when the user is sitting on the sheet-like seat part 2 or when the seat part 2 is folded and a wire member 16 that connects between the swing arm member 12 and the cam member. The swing arm member 12 is mounted on a cross frame 28, and when the sheet-like seat part 2 is folded for the purpose of carrying the wheelchair body, the cross frame 28 is extended in the vertical direction, with the cam member allowing the tire to rotate.COPYRIGHT: (C)2015,JPO&INPIT【課題】持ち運ぶ場合に制動力を解除してタイヤを回転させながら移動できる補助ブレーキおよびこの補助ブレーキを備えた車椅子を提供する。【解決手段】シート状の座部2の下面に接離自在に揺動アーム部材12を備え、シート状の座部2から利用者が立ち上がろうとした場合に、タイヤの周面に食い込む姿勢となって、タイヤの回転を阻止するとともに、シート状の座部2に利用者が座っている場合またはシート状の座部2を折り畳んだ場合に、タイヤの周面から離反する姿勢となって、タイヤの回転を許容するカム部材と、揺動アーム部材12とカム部材との間を連結するワイヤー部材16と、を備えており、揺動アーム部材12が、クロスフレーム28に取り付けられており、車椅子本体を持ち運ぶためにシート状の座部2を折り畳んだときに、クロスフレーム28が鉛直方向への長さが延長され、カム部材がタイヤの回転を許容する。【選択図】図3
