CONSTITUTION: A fixing structure of a manhole cover comprises many through holes(12) formed along the circumference of a manhole cover(10), a stepped joint extended on the center of the through holes(12), a stepped joint groove(14a) formed longitudinally on the stepped joint, a fixing member(30) provided with a hanger on the lower end and coupled to the through holes(12) by a spring elastically, a projection formed on a head of the fixing member(30) and fitted to the stepped joint groove(14a), and a hanging groove formed under a bearing frame(20) to fix or unfix the hanger by rotating the fixing member(30), so that the manhole cover(10) is fixed through the fixing member(30) to prevent separation from the bearing frame(20).
