PROBLEM TO BE SOLVED: To provide a brake pressure control device that can reduce a product cost and size and can collect leaked brake fluid. SOLUTION: By utilizing a thickness of a heat sink 28, an oil reservoir concave part 28d which opens toward a motor attaching face 1a is formed in the heat sink 28, and an oil reserving chamber S28 is provided between the motor attaching face 1a and the oil reservoir recess part 28d. Therefore, since another oil reserving chamber is not needed to be formed inside a housing 1, the housing 1 can be reduced in size. Further, by attaching the heat sink 28 in such a posture as to oppose to the motor attaching face 1a, the oil reserving chamber S28 is formed. Thereby, other components to form the oil reserving chamber S28 are unnecessarily provided especially and thus, burden to process these components can be omitted. As a result, the product cost and size can be reduced. COPYRIGHT: (C)2010,JPO&INPIT |
