PROBLEM TO BE SOLVED: To provide a wheelchair with an automatic brake which has structure of suppressing the play of the brake to be little, which stably maintains a brake effect of surely blocking forward and backward movement until a person to get on is completely seated, and is therefore excellent in safety.SOLUTION: The wheelchair with an automatic brake is characterized in that: in the seating face of the wheelchair, one-side ends of a pair of long bodies 202 for suspension support and traction are respectively connected to both sides of a L-shaped auxiliary seating face 201 and the auxiliary seating face 201 are made turnable for a prescribed amount the other ends of the respective long bodies 202 are connected to operation end portions of spring-energized brake operation levers 203 a cam member 206 is provided in a shaft mounting part of each brake operation lever 203 so as to be turnable together with the brake operation levers 203 and the wheelchair with an automatic brake further includes a V-shaped brake 205 being configured in such a manner that: in both sides of a wheelchair body 100, one-side ends of a pair of brake plates 205-1, 205-2 are shaft-mounted identically and are formed into V shape a cam member 206 is located in the inner angle portion of the V shape the inner angle is enlarged/reduced by a spring mechanism 205-3 and the cam member 206, consequently open ends of the brake plates 205-1, 205-2 are abutted on the outer periphery of a driving wheel.COPYRIGHT: (C)2012,JPO&INPIT【課題】ブレーキの遊びを僅少に抑える構造で、かつ乗る人が完全に着座するまで前後移動を確実に阻止するブレーキ効果を安定して維持する安全性に優れた自動ブレーキ付車椅子を提供する。【解決手段】車椅子の座面内にL型の補助座面201の両側に吊支持牽引用の一対の長尺体202の各一端部を連結して補助座面201を所定量回動可能にし、バネ付勢したブレーキ操作レバー203の操作端部に各長尺体202の他端部を連結し、各ブレーキ操作レバー203の軸装着部にカム部材206をブレーキ操作レバーと併回動可能に設け、車椅子本体100の両側部に一対のブレーキプレート205-1、205-2の一端部を同一に軸装着してV型に形成し内角部にカム部材206を位置させバネ機構205-3とカム部材206により角拡縮してブレーキプレート205-1、205-2の開放端部を駆動車輪の外周部に当接するV型ブレーキプレート205を設けた。【選択図】図1
