PROBLEM TO BE SOLVED: To provide a fluid pressure control unit of a braking device capable of thinning a unit block and improving degree-of-freedom of layout of components when mounted on a vehicle.SOLUTION: The fluid pressure control unit of a braking device includes: a master cylinder 21 for supplying brake fluid to a brake caliper 12; a reservoir 23 for retracting the brake fluid of the brake caliper 12; a main path 40 for connecting the master cylinder 21 to the brake caliper 12 through brake piping 39; a normally opened supply side control valve 25 for controlling the flow of the brake fluid through the main path 40; a reserve path 44 branching from the main path 40, and connected to the reservoir 23; and a normally closed discharge side control valve 26 for controlling the flow through the reserve path 44. The master cylinder 21, the supply side control valve 25 and the discharge side control valve 26 are disposed in a unit block 27 so that the respective axes o1, o2, o3 are located in a virtual planar block having a thickness substantially equal to a diameter of the master cylinder 21. |
