Abstract: A hydraulic device comprises a base member, a piston, a seal ring, and an intermediate member. The base member includes a cylinder bore and an annular groove. The annular groove includes a first inner surface and a second inner surface. The piston is movable relative to the base member from a rest position toward an actuated position in a second direction opposite to a first direction. The piston is movable relative to the base member from the actuated position toward the rest position in the first direction. The seal ring includes a first axial surface facing in the first direction and a second axial surface facing in the second direction. The seal ring is provided in the annular groove so as to define a clearance between the first axial surface and the first inner surface. The intermediate member is provided in the clearance.
