To provide a hydraulic master cylinder device for bar handle vehicle in which change in lever ratio can be performed by a simple operation.SOLUTION: A hydraulic pressure master cylinder device 1 comprises a hydraulic master cylinder 4, an operation lever 6, and a push rod 8 which is interposed between the operation lever 6 and a piston 7 of the hydraulic master cylinder 4. A connection member 5 is rotatably connected to lever brackets 4e, 4e of the hydraulic master cylinder 4 via a first pivot 16, and the operation lever 6 is rotatably connected to the connection member 5 via a second pivot 18. The connection member 5 forms lever ratio change holes 5h, 5i, 5j in a vehicle width direction at an intermediate position of a first pivot insertion hole 5d and a second pivot insertion hole 5e, and inserted a lever ratio change pin 17 into a pin hole 4g formed in the brackets 4e, 4e, and any one of the lever ratio change holes 5h, 5i, 5j, thereby enabling lever ratio change.SELECTED DRAWING: Figure 1

    【課題】レバー比の変更を簡単な作業で行う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】液圧マスタシリンダ装置1は、液圧マスタシリンダ4と、操作レバー6と、操作レバー6と液圧マスタシリンダ4のピストン7との間に介装されるプッシュロッド8とを備える。液圧マスタシリンダ4のレバーブラケット4e,4eに第1ピボット16を介して連結部材5を回動可能に連結し、該連結部材5に第2ピボット18を介して操作レバー6を回動可能に連結する。連結部材5は、第1ピボット挿通孔5dと、第2ピボット装着孔5eとの中間位置に、レバー比変更孔5h,5i,5jを車体幅方向に形成し、レバーブラケット4e,4eに形成したピン孔4gとレバー比変更孔5h,5i,5jのいずれか1つとにレバー比変更ピン17を挿通することにより、レバー比を変更可能とする。【選択図】図1
