Zusammenfassung:	PURPOSE:To form a small-sized hydraulic pressure generating source such as a pump by exceedingly reducing the leak of working liquid. CONSTITUTION:The brake liquid in a master cylinder 47 is sent into a brake cylinder 45, passing through an opening/closing valve 56 for feed, and a brake is operated. In this state, an electromagnetic force is generated by the supplied electric current, in a linear solenoid 67, and a control lever 90 is turned in the counterclockwise direction around a spherical part 90a by the electromagnetic force, and the opening/closing valve 56 for feed is closed. Then, the control lever 90 turns in the clockwise direction around the spherical part 90b, and an opening/closing valve 78 for discharge is opened. Accordingly, the brake liquid pressure of the brake cylinder 45 lowers. The force of a pin 96 increases according to the compressed brake hydraulic pressure Pw, and the control lever 90 turns in the clockwise direction around the spherical part 90b, and the opening/closing valve 78 for discharge is closed. Accordingly, the brake hydraulic pressure is adjusted to the value corresponding to the supplied electric current for the solenoid 67.
