PROBLEM TO BE SOLVED: To provide a reservoir tank of a fluid-pressure master cylinder that suppresses creases from occurring in a bellows part when filling operating fluid thereinto while vacuuming a hydraulic path and allows the bellows part to automatically return to an original shape after filling the operating liquid.SOLUTION: A diaphragm 9 comprises a flange part 9a, a bellows part 9b, and a plane part 9c. The bellows part 9b comprises long side parts 9h and short side parts 9i formed linearly inside the flange part 9a and bent parts 9j connecting the long side parts 9h to the short side parts 9i. In the long side parts 9h and the short side parts 9i are formed thick wall reinforcement parts R1 and in the bent parts 9j are formed constricted parts 9k recessed toward a reservoir main body.SELECTED DRAWING: Figure 2

    【課題】油圧経路を真空引きしながら作動液を充填する際に、蛇腹部に折り皺が発生することを抑制し、作動液充填後に蛇腹部が元の形状に自動的に復帰することができる液圧マスタシリンダのリザーバタンクを提供する。【解決手段】ダイヤフラム9は、フランジ部9aと、蛇腹部9bと、平面部9cとを備える。蛇腹部9bは、フランジ部9aの内側に直線状に形成される長辺部9h及び短辺部9iと、長辺部9hと短辺部9iとを繋ぐ屈曲部9jとを備える。長辺部9h及び、短辺部9iに肉厚補強部R1を設けるとともに、屈曲部9Jに、リザーバ本体側に向けて凹状となるくびれ部9kを設ける。【選択図】 図2
