VEHICLE BRAKE DEVICE

摘要

A vehicle brake device that can, without using a dedicated heat radiator and heat radiation plate, efficiently radiate heat of electronic components requiring heat radiation and that can use a circuit board having a sufficient margin for component arrangement. In an electronic control unit (102) for brake control, a circuit board (103) that has electronic circuits formed on it and a coil carrier (104) that holds coils (5a-5h) used for solenoid switchover valves (2a-2h) are received in a housing (4) for control unit and attached to and integrated with a hydraulic unit (101). The coil carrier (104) is constructed from a heat conductive material and has a transistor (16) attached to it for heat radiation.
