PROBLEM TO BE SOLVED: To provide a vehicular liquid pressure master cylinder capable of improving durability of a boot.SOLUTION: A piston 3 is internally inserted into a cylinder hole 2a formed in a cylinder body 2, and a push rod 10 to push the piston 3 is movably disposed on a cylinder hole opening side of the piston 3. A cylindrical collar member 13 is attached via annular seal members 12 and 12 to the outside of a shaft part 10b of the push rod 10 projecting from the cylinder hole opening. One end of the boot 14 is attached to the cylinder hole opening side of the cylinder body 2, and the other end is attached to an outer peripheral surface of the collar member 13.

    【課題】 ブーツの耐久性の向上を図ることができる車両用液圧マスタシリンダを提供する。【解決手段】 シリンダボディ2に形成したシリンダ孔2aにピストン3を内挿し、ピストン3のシリンダ孔開口側に、ピストン3を押動するプッシュロッド10を移動可能に配置する。シリンダ孔開口部より突出するプッシュロッド10の軸部10bの外側に、筒状のカラー部材13を環状のシール部材12,12を介して取り付ける。ブーツ14の一端をシリンダボディ2のシリンダ孔開口側に取り付け、他端をカラー部材13の外周面に取り付ける。【選択図】 図1
