PURPOSE: A solenoid actuator for a vehicle brake is provided to smoothly operate opening and closing of a main passage by preventing increase of pressure because hydraulic pressure is concentrated in a flowing space when the hydraulic pressure is supplied from a supply side to an actuating side. CONSTITUTION: A solenoid actuator(100) for a vehicle brake includes a main passage, a supply passage(2), a cylindrical coupling member(23), and an electromagnet(27). In order to pass and communicate the main passage and the supply passage through a flowing space(11), a valve(10) is comprised. The cylindrical coupling member has a nonmagnetic body(21) in the front and a magnetic body(22) in the back. A permanent magnet(25) on which a sealing packing is attached is successively inserted inside the cylindrical coupling member. The cylindrical coupling member is coupled to the flowing space of the valve. The electromagnet is actuated in a state where the hydraulic pressure is supplied to the main passage, the flowing space, and the supply passage in order. |
