Abstract:
A method of manufacturing a hydraulic control apparatus comprising:a hydraulic unit for accommodating a hydraulic mechanism for adjusting brake fluid pressure to be used for vehicle controlling; and an actuator driving circuit unit integrally assembled with the hydraulic unit, having a circuit unit housing including: an operation portion for accommodating an electronic control actuator for controlling the hydraulic mechanism; and an electronic substrate portion for being separated from the operation portion, and for accommodating an electronic substrate for controlling a brake fluid pressure generating actuator, wherein the circuit unit housing is made up of a case fixed to a hydraulic unit housing of the hydraulic unit and a cover for covering the case, the method comprising: superimposing an edge portion of the cover on an edge of the case; and bonding the case and the cover by using vibrating welding by vibrating at least one of the case and the cover, wherein the edge portion of the case has an inside convex portion to be bonded with the cover and an outside convex portion shorter than the inside convex portion formed adjacent to the inside convex portion with a concave portion interposed therebetween over the whole bonding portion.
