PROBLEM TO BE SOLVED: To provide a wheelchair having a positioning mechanism for easily positioning a wheel in a special separating position, by which the wheel is easily placed in the special separating position in order to form the clearance necessary for getting on and off a seat section, to improve the positioning of the wheel and enhance the convenience for use.SOLUTION: In the wheelchair, a seat part 2 is disposed on a frame 1, and circular wheels 5 are disposed on each of the left and right side sections of the frame. The wheel chair includes a wheel separation mechanism 7 for separating a special fan-shaped section 5a of the wheel, which includes an outer circumferential part of the wheel, from the remaining section 5b excluding the special section, in the special separating position F in order to form the clearance K required for a person to get on and off the seat, and has the positioning mechanism 10 for positioning the wheel in the special separating position.COPYRIGHT: (C)2011,JPO&INPIT【課題】車輪を特定の分離位置に位置決め可能な位置決め機構を設けてなるから、車輪を座部に対する乗り降りに必要な開放空間を形成するための特定の分離位置に容易に位置決めすることができ、車輪の位置決め作業性を高めることができ、使用の利便性を高めることができる。【解決手段】フレーム1に座部2を配設すると共にフレームの左右両側部に円形状の車輪5を配設し、座部に対する乗り降りに必要な開放空間Kを形成するための特定の分離位置Fにおいて円形状の車輪を車輪の外周の一部を含む扇形状の特定部分5aと特定部分を除いた残余部分5bとを分離可能とする車輪分離機構7を設け、車輪を特定の分離位置に位置決め可能な位置決め機構10を設けてなる。【選択図】図1
