A hydraulic reservoir in a tandem master cylinder includes a main portion defining a fluid reservoir chamber for reserving brake fluid, two fluid supply portions defining fluid paths under the main portion, the fluid supply portions being contiguous with the main portion and an opening formed at the top, the two fluid supply portions being connected to two fluid connection portions of a tandem master cylinder body. The main portion is so shaped that one space defined by one cross section taken along one line normal to the central axis of the main portion, viewing from the top along the central axis is substantially equal to, or includes, another space defined by another cross-section taken along another line normal to the central axis of the main portion, the one cross-section being nearer the opening, and the fluid paths are so shaped that a further space defined by a futher cross-section taken along a further line normal to the central axis of the main portion at the bottom includes at least respective one parts of the cross-sections of the fluid paths at the bottom of the main portion.
