A brake hydraulic pressure supply unit (10) is provided with: a hydraulic pressure generation device (12) for generating hydraulic pressure in a hydraulic pressure chamber (12C) formed in a cylinder (12A) by driving a piston (12B), which slides in the cylinder (12A), by means of an electric motor (11); and a housing (13) in which a liquid path connected to the hydraulic chamber (12C) is formed. Furthermore, in the brake fluid pressure supply unit (10), both the electric motor (11) and the cylinder (12A) are attached to the housing (13), and the electric motor (11) is positioned above the cylinder (12A) in the vertical direction in a posture in which the brake fluid pressure supply unit (10) is mounted on the vehicle. Thus, even if liquid leaks from the cylinder (12A), the leaked liquid can be prevented from entering the motor (11). Therefore, the reliability of the brake fluid pressure supply unit (10) can be improved without causing an abnormality in the operation of the electric motor (11).

    制动液压供给单元(10)具备:液压产生装置(12),由电动机(11)驱动在缸(12A)内滑动的活塞(12B),从而使形成于缸(12A)内的液压室(12C)产生液压;以及壳体(13),形成有连接到液压室(12C)的液路。而且,制动液压供给单元(10)中,电动机(11)与缸(12A)均安装在壳体(13)上,在搭载于车辆的姿态下,电动机(11)位于比缸(12A)靠铅垂方向上方的位置。由此,即使从缸(12A)漏出液体,也能够防止漏出的液体侵入电动机(11)的内部。因此,不会对电动机(11)的动作造成异常,能够提高制动液压供给单元(10)的可靠性。
