A vehicle brake hydraulic pressure control apparatus includes: a control unit into which a base body, a motor and a controller housing are unitized and in which the motor and the controller housing are disposed so as to hold the base body therebetween; and a support device interposed between a vehicle body and the control unit. The support device has a lower mount member fixed to a lower surface of the base body that becomes vertical when the control unit is mounted on the vehicle body and a bracket that connects the lower mount member with the vehicle body. A center of gravity of the control unit is situated on the base body. The lower mount member is supported by the bracket to be situated at an intersection point between a vertical line passing through the center of gravity and the lower surface of the base body.
