Zusammenfassung:	PURPOSE: An expansion and contraction apparatus of an automatic temperature regulating valve for heating is provided to reduce the length of a valve body by coupling a shape memory expansion spring and an extensible compression spring to the space of a valve chamber in layers. CONSTITUTION: An expansion and contraction apparatus of an automatic temperature regulating valve for heating comprises shape memory expansion springs(114) and extensible compression springs(115). The shape memory expansion springs are inserted into the outer surface of one end of a valve guide socket(121) and are supported by a spring hanger(113) and one surface of a flange unit(111a) of a valve disc(111). One ends of the extensible compression springs are hung on multiple holes of the flange unit of the valve disc, and the other ends are hung on edge holes(113a) of the spring hanger.
