To provide a reservoir having a connection structure with a cylinder body which enables reduction of influence of deformation caused by temperature while maintaining a simple structure achieving low costs.SOLUTION: A reservoir (2) mounted on a vehicle includes: a body (20) which stores a brake fluid; and a connection part (22) which is connected to a connection hole (31) provided at a cylinder body (3) through a grommet (5) so as to circulate the brake fluid between the cylinder body (3) and the body (20). The connection part (22) has: a main pipe part (22a) which protrudes from the body (20) and in which the brake fluid circulates; and an outer ring part (22b) which restricts a position of the grommet (5). In a root portion of the main pipe part (22a), on at least one of the vehicle front side and the vehicle rear side, a curved surface part (22e) or a conical surface is formed at the outer peripheral surface side of the main pipe part (22a). At the outer ring part (22b), the grommet (5) is not disposed on the curved surface (22e) or the conical surface and is spaced a predetermined distance apart from the root portion.SELECTED DRAWING: Figure 1

    【課題】簡素かつ低コストの構造を維持しつつ、温度による変形の影響を軽減できるシリンダボデーとの接続構造を有するリザーバを提供する。【解決手段】車両に搭載されるリザーバ(2)は、ブレーキ液を貯留する本体(20)と、シリンダボデー(3)と本体(20)との間でブレーキ液を流通させるように、シリンダボデー(3)に設けられた接続孔(31)にグロメット(5)を介して接続される接続部(22)とを備える。接続部(22)は、本体(20)から突出し、ブレーキ液が流通する主管部(22a)と、グロメット(5)の位置を規制する外環部(22b)とを有する。主管部(22a)の根元部分には、少なくとも車両前方側または車両後方側に、主管部(22a)の外周面側に曲面部(22e)または錐面部が形成されている。外環部(22b)は、グロメット(5)が曲面部(22e)または錐面部に配置されず、かつ根元部分と所定の間隔をおいている。【選択図】図1
