PURPOSE: A three-dimensional vibration isolator is provided to prevent vibration generated in a vertical direction and a horizontal direction, protect vibration reducing components, and to enlarge a life of the vibration isolator. CONSTITUTION: A three-dimensional vibration isolator includes a base(10), a fluid chamber(30) mounted at the base and having an opening formed on an upper surface, a lifting block(20) mounted between the base and a vibration body and having a piston rod(22) inserted through the opening of the fluid chamber and a vibration isolation chamber, two or more springs(40) connected between a lower contour of the lifting block and the surface of the base and vertically expanding by vertical vibration of the vibration body, a vibration isolating rubber(50) fit in an inner wall of the vibration isolation chamber and horizontally expanding by the vibration of a direction of the vibration body, a connection plate(52) for expanding the vibration isolating rubber through horizontal vibration, and a fixing part for fixing the vibration body to the connection plate.
