To provide a reservoir tank which can facilitate bleeding at the time of injection of an operation liquid while reducing waste of the operation liquid to be injected.SOLUTION: A reservoir tank which stores an operation liquid supplied to a master cylinder includes a tank body having a storage chamber therein, an operation liquid injection port provided on an upper surface of the storage chamber, and a plurality of ribs that partition the storage chamber, where the upper surface of the storage chamber has an inclined part which has a V-shaped cross section or a U-shaped cross section having an apex that gradually becomes higher toward the operation liquid injection port in a longitudinal direction of the storage chamber and is continuous in a longitudinal direction, the upper end of the ribs is connected to the upper surface, one end in a width direction crossing the longitudinal direction of the ribs is connected to a wall part extending to the longitudinal direction, the apex of the inclined part is positioned at a position to which the ribs are not connected, an angle formed by a first surface positioned on the operation liquid injection port side in the ribs and the longitudinal direction is formed at a right angle or larger, and an angle formed by a second surface directing the opposite side to the operation liquid injection port in the ribs and the longitudinal direction is formed into an obtuse angle.SELECTED DRAWING: Figure 4
【課題】注入する作動液の無駄を低減しつつ、作動液注入時のエア抜きを容易にすることが可能なリザーバタンクを提供する。【解決手段】マスタシリンダへ送給する作動液を貯留するリザーバタンクにおいて、内部に貯留室を有するタンク本体と、貯留室の上面に設けられた作動液注入口と、貯留室を仕切る複数のリブと、を備え、貯留室の上面は、貯留室の長手方向に沿って作動液注入口に向けて漸次高さが高くなるとともに、長手方向に沿って連続する頂部を有する断面V字状又は断面U字状の傾斜部を有し、リブの上端部は上面に連結され、リブの長手方向に交差する幅方向の一端部は長手方向へと延在する壁部に連結され、傾斜部の頂部はリブが連結されていない位置に設けられ、リブにおける作動液注入口側に位置する第1の面と長手方向との成す角が直角以上に形成され、リブにおける作動液注入口とは反対側を向く第2の面と長手方向との成す角が鈍角に形成される。【選択図】図4
