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.
