PURPOSE: An anti-releasing spring nut is provided to continuously ensure an anti-releasing function, reduce a manufacturing cost. CONSTITUTION: A thread(3) is formed passing through the inside of the groove(2) of an anti-releasing spring nut(1). The spring nut absorbs external vibration and shock and elastically moves, thus the thread of the groove makes tight contact with the surface of the thread of the bolt due to strong frictional force. The spring nut is formed in a spring coil(4) shape, contracts and expands due to external temperature, makes tight contact with the thread of the bolt, raises contact pressure, thus is not released.
