PROBLEM TO BE SOLVED: To provide a wheelchair for rehabilitation capable of gradually transmitting an initial force generated when a user starts pedaling, and adjusting the pedaling force according to recovery of the user.SOLUTION: In a wheelchair 1 for rehabilitation, a body frame 2 comprises a travel part which includes a seat part 5 on which a trainee sits, a backrest part 6, a pair of left and right front wheels 3, 3, and a pair of left and right rear wheels 4, 4. A pair of left and right pedals 7, 7 for placing legs of the trainee is disposed at the front lower part of the seat part 5. The left and right pedals are connected to a pair of left and right hydraulic cylinders 11L, 11R. One of the left and right hydraulic cylinders is communicated with one of left and right hydraulic actuators 60 through an oil passage. The one of the left and right hydraulic actuators 60 is communicated with the other of the left and right hydraulic actuators 60 through the oil passage. The other of the left and right hydraulic actuators 60 is communicated with the other of the left and right hydraulic cylinders 11 through the oil passage. The lowering operation of one of left and right pedals 7 rotates the left and right rear wheels 4, 4 and raises the other pedal 7.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2016,JPO&INPIT【課題】ペダルをこぐ初期の力を徐々に伝えることができ、そのこぐ力を回復に合わせて調節できるリハビリ用車椅子を提供しようとする。【解決手段】機体フレーム2に、訓練者が座る座部5と背もたれ部6と、左右一対の前輪3・3と後輪4・4とからなる走行部を備えたリハビリ用車椅子1であって、前記座部5の前下方には訓練者の足を載せる左右一対のペダル7・7が配置され、該左右のペダルはそれぞれ左右一対の液圧シリンダ11L・11Rと連結され、該左右一方の液圧シリンダは油路を介して左右一方の液圧アクチュエータ60と連通され、該左右一方の液圧アクチュエータ60は油路介して左右他方の液圧アクチュエータ60と連通され、該左右他方の液圧アクチュエータ60は油路を介して左右他方の液圧シリンダ11と連通され、左右一方のペダル7の下降動作により、左右の後輪4・4を回転させるとともに、左右他方のペダル7を上昇させる。【選択図】図9
