PROBLEM TO BE SOLVED: To provide the brake mechanism of a walking auxiliary vehicle capable of running at a speed corresponding to the walking capacity of a user, capable of reducing the load applied to the foot or waist of the user to reduce the fatigue of the user during walking and capable of smoothly performing walking and running.SOLUTION: The brake mechanism of the walking auxiliary vehicle 1 is constituted so that the base end part of the brake lever 12 arranged to the front side lower part of the handle lever 11 of a handle part 10 is pivotally mounted on the brake support part 14d fixed to the handle lever 11 of the handle part 10 in an up and down freely revolvable manner and the rotation of a rear side wheel 7 is braked by the brake member 9a of the brake mechanism 9 cooperated with the brake operation of the brake lever 12. A hook member 30, with which the free end side of the brake lever 12 is locked, is provided to the handle lever 11 and lever hooking parts 30c and 30d, with which the free end side of the brake lever 12 is locked, are provided to the hook member 30. Further, the position of a lever hooking member 31 is provided so as to be regulated to a plurality of positions set at a predetermined interval with respect to the longitudinal direction of the hook member 30.COPYRIGHT: (C)2013,JPO&INPIT【課題】この発明は、利用者の歩行能力に応じた速度で走行することができ、利用者の足や腰等に与える負担を小さくして、歩行時の疲労を軽減することができるとともに、歩行及び走行がスムースに行える歩行補助車のブレーキ機構の提供を目的とする。【解決手段】ハンドル部10のハンドル杆11に固定したブレーキ支持部14dに、該ハンドル杆11の前側下部に配置したブレーキ杆12の基端部を上下回動自在に枢着し、ブレーキ杆12の制動操作と連動する制動機構9の制動部材9aにて後側車輪7の回転を制動する歩行補助車1のブレーキ機構であって、ハンドル杆11に、ブレーキ杆12の遊端側が係止されるフック部材30を設け、該フック部材30に、ブレーキ杆12の遊端側が係止される杆掛け部30c,30dを設けている。また、杆掛け部材31の位置を、フック部材30の長手方向に対して所定間隔を隔てて設定した複数の位置に移動調節可能に設けている。【選択図】図19
