PURPOSE: A structure for coupling a water supply control valve to a filter for a boiler is provided to improve sealing efficiency by rotatably coupling the filter to one side of the water supply control valve. CONSTITUTION: A stepped unit(32) is formed in the front of a filter containing unit(31) formed at a filter housing(30). A thread unit(33) is formed at the outer end of the filter housing. A contact plate(42) is installed at the rear of a filter(40) coupled to the filter containing unit, and adheres closely to the stepped unit. A screw unit(43) is formed at the rear of the filter, and is coupled to the thread unit.
