A device for fixing coil assemblies of solenoid valves for an electronically controlled brake system in which a bobbin of each coil assembly is firmly coupled to a housing of an electric control unit (ECU) by fixing bosses provided at the bottom of the bobbin and fixing grooves formed at the bottom of the ECU housing to receive the fixing bosses, and cases enclosing the bobbin are elastically supported by the elastic support member. Accordingly, the bobbin and cases can be firmly fixed to the ECU housing. Vertical movement of the cases is also restrained. Accordingly, magnetic flux passing through the cases is constant. A certain gap is also maintained between the bobbin and an upper one of the cases. Therefore, it is possible to prevent the resistance of the coil wound around the bobbin from being varied due to the weight of the upper case.
