    Abstract: A gas control unit for a boiler includes a hollow housing; a solenoid; a rod; opening and shutting means that is disposed at the lower end of the rod to open and shut a gas outlet; and a spring between the housing and the opening and shutting means so as to elastically urge it downward. A coupling member is formed at the lower end of the rod and a coupling groove into which the coupling member is inserted is formed in the opening and shutting means so as to allow movement. The opening and shutting means is coupled to the rod through the use of the coupling member and the coupling groove, the opening and shutting means can move within a predetermined range about the coupling member with an application of an external force.
