To provide a hydraulic master cylinder device for bar handle vehicle which can easily change a lever ratio without attachment/detachment of a component.SOLUTION: An operation lever 4 is configured from a lever body 16 and a knocker 17, and a spring member 20, which energizes the operation lever 4 to a handle bar side around a pivot 15, is provided between the lever body 16 and the knocker 17. A columnar piece member 19 comprising an engagement protrusion 19b is mounted to a projection end 5a of a push rod 5. The knocker 17 is provided with a storage part 17d which rotatably and movably stores the piece member 19. The engagement protrusion 19b is formed on a vehicle body upper side end face of the piece member 19, and three engaging grooves 16g, 16h, 16i, which are engaged with the engagement protrusion 19b, are provided on a cylinder hole opening side face of an arm part 16d on a vehicle upper side of the lever body 16. A space part E1, in which the engagement protrusion 19b can be moved when rotating the lever body 16 to a vehicle body front side, is provided at vehicle body rear side ends of the engaging grooves 16g, 16h, 16i.SELECTED DRAWING: Figure 1

    【課題】部品を着脱することなく容易にレバー比を変更することができるバーハンドル車両用液圧マスタシリンダ装置を提供する。【解決手段】操作レバー4をレバー本体16とノッカー17とで構成し、レバー本体16とノッカー17との間に、操作レバー4をピボット15を中心にハンドルバー側に付勢するスプリング部材20を設ける。プッシュロッド5の突出端部5aに、係合突部19bを備えた円柱状の駒部材19を装着する。ノッカー17に、駒部材19を回動可能、且つ、移動可能に収容する収容部17dを設ける。駒部材19の車体上部側端面に、係合突部19bを形成し、レバー本体16の車体上部側の腕部16dのシリンダ孔開口側面に、係合突部19bに係合する3個の係合溝16g,16h,16iを設ける。係合溝16g,16h,16iの車体後方側端部に、レバー本体16を車体前方に回動させた際に、係合突部19bが移動可能な空間部E1を備える。【選択図】図1
