とする車両用ブレーキ油圧制御装置。 A partition wall supported by a step provided in the middle of the cylinder hole is fitted into a bottomed cylinder hole bored in the casing in order to divide the inside of the cylinder hole into a first cylinder part and a second cylinder part, A lid member that presses and fixes the partition wall toward the stepped portion by contacting a cylindrical sleeve that is integral with or separate from the partition wall is attached to the open end of the cylinder hole, and the first cylinder portion has an input hydraulic chamber. A first piston that defines a control chamber on the partition wall side and that can communicate with a control hydraulic pressure source is slidably connected to the opposite side of the partition wall, and an output hydraulic chamber is arranged in the second cylinder portion on the partition wall side. A spring chamber is defined on the side opposite to the bulkhead.
Four brake hydraulic modulators are provided in a common casing, each consisting of a second piston that is slidably connected to a piston, each output hydraulic chamber is individually connected to each wheel brake, and two pairs of input hydraulic chambers are connected in tandem. In a vehicle brake hydraulic control device connected to both output ports of a master cylinder, a pair of brake hydraulic modulators each having an input hydraulic chamber communicating with the same output port of the master cylinder are placed adjacent to each other, and each brake hydraulic modulator is connected to a casing. 1. A brake hydraulic control device for a vehicle, wherein the lid member is installed in parallel to a casing of a pair of brake hydraulic modulators.
