The vehicular brake hydraulic control device includes a plurality of electromagnetic valves arranged at regular intervals on a first attaching plane of a body, and coil assemblies fit over each of the electromagnetic valves, wherein the coil assemblies adjacent to one another are arranged apart by a predetermined gap. The vehicular brake hydraulic control device further includes a rubber seal having a linear segment formed in a convex sectional shape swelling outwardly of the first attaching plane of the body, in which the hem of the seal is sandwiched between the coil assemblies and the first attaching plane of the body, and the apex of the seal enters between the coil assemblies adjacent to one each other.

Vehicular brake hydraulic control device

A brake fluid pressure maintaining apparatus for a vehicle, having: a master cylinder; a check valve; and, a normally-open-type electromagnetic valve including an electromagnetic coil, a fixed core, and a movable core, and in the brake fluid pressure maintaining state, it is closed and, in the brake fluid pressure no-maintaining state, it is always opened, and by changing the value of the current, an attracting force is changed; by setting the attracting force at a given value, the brake fluid pressure to be maintained on the wheel brake side is set; and, when it is closed, in case where the brake fluid pressure of the wheel brake is higher than the attracting force of the given value, it is opened against the attracting force to thereby reduce the brake fluid pressure of the wheel brake down to the given value.
