Abstract
In a brake hydraulic controller for controlling a hydraulic pressure from a master cylinder operative to a wheel brake, the controller includes a base, a normally open electromagnetic valve for connecting the master cylinder and the wheel brake, a reservoir, a normally closed electromagnetic valve for connecting the wheel brake and the reservoir, a return pump for returning hydraulic fluid received from the reservoir to the master cylinder, a damper, and a cover for covering the normally open and closed electromagnetic valves, the reservoir, and the damper with a surface of the cover. The cover includes a seal groove and a sealing member fitted to the seal groove for elastically contacting the surface. The brake hydraulic controller can minimize the number of parts required for waterproofing and reduce the number of manhours required for assembling.
