PROBLEM TO BE SOLVED: To solve problems of a conventional wheelchair that, when air in tire of a wheelchair is reduced, brake force can be held by press force from three directions, but when air pressure is reduced, tires are deformed and rolling resistance becomes larger and results in an increased load of an operator during travel, and it is determined whether or not air pressure is in a proper range in a post-process, and it is impossible to determine the air pressure simultaneously with press-in of air, and there is a cover for covering the surrounding area of a handle grip part, but it cannot cover hands of the operator during an overturn.SOLUTION: A tire air pressure display is attached to an air supply mouth ring of a wheel of a wheelchair, and comprises: a mouth ring attachment part; an air press-in part; and an air pressure display part. From the air press-in part, air is pressed into the tire, and pressure equal to that in the tire can be displayed on the air pressure display part.
【課題】 従来品は、車椅子のタイヤの空気が減った場合においても3方向からの押し付け力でブレーキ力を保持できるものであるが、空気圧が減っているとタイヤが変形して転がり抵抗が大きくなり、走行時の操作者の負担は大きい。また、空気圧が適正かどうかを後工程にてチェックするもので、空気の圧入と同時にチェックすることはできない。さらに、ハンドルグリップ部周辺を覆うカバーはあるが、転倒時等に手は保護できない。【解決手段】 車椅子の車輪の空気供給用口金に取り付けるもので、口金取付部と、空気圧入部と、空気圧表示部とから構成され、前記空気圧入部よりタイヤ内に空気を圧入しながら、タイヤ内の圧力と同じ圧力を前記空気圧表示部に表示することができることを特徴とする。【選択図】図1
