Abstract
A hydraulic pressure controller includes: a base; a n electromagnetic valve mounted on the base and including a guide cylinder protruding from the base, a coil unit having a bobbin surrounding the guide cylinder and a coil wound on the bobbin, and a magnetic path forming frame connecting magnetically a first end and a second end of the guide cylinder; a reservoir and a damper arranged with the electromagnetic valve on the base; and a cover covering the electromagnetic valve, the reservoir and the damper, in which the cover includes a frame coupled to the base, the frame surrounding the electromagnetic valve, and a skirt portion formed integrally with the frame, the skirt portion covering the reservoir and the damper. The hydraulic pressure controller is light in weight and is improved in assembling efficiency. The hydraulic pressure controller has a reservoir water-proofing structure which is capable of preventing water from entering an outside air communicating chamber of the reservoir.
