Patent ID: 8141961

Claim:
A vehicle-use brake device in which first electromagnetic open/close valves changing over communication/interruption between master cylinders which output liquid pressures corresponding to operations of brake operators and wheel brakes, and second electromagnetic open/close valves changing over communication/interruption between liquid-pressure generation means which are configured to generate liquid pressures due to operations of electrically-operated actuators and the wheel brakes are arranged in a base body, comprising: output ports connected to the wheel brakes are formed in one flat side surface of the base body, and the first and second electromagnetic open/close valves which have operational axes thereof arranged on a first plane orthogonal to said one side surface are mounted on one surface of the base body orthogonal to said one side surface from the same direction, wherein stroke simulators which apply pseudo reactional forces corresponding to operation quantities of the brake operators to the master cylinders at the time of closing the first electromagnetic open/close valves are arranged in the base body with stroke directions thereof set parallel to the first plane.
