PURPOSE: An apparatus for coupling a heat sink is provided to easily fix and dissemble the heat sink and a printed circuit board by a simple operation that an operator presses an elastic supporting unit and transfers a support plate. CONSTITUTION: A shaft(11) is inserted into a coupling hole(3) and a combination hole(6), having a fixing groove(13) of a ring type at an end side passing through the combination hole. A support plate(16) is in contact with a lower surface of a printed circuit board(5), having an incision groove to which the shaft is inserted from a side of the support plate. A clamp member(15) is bent and extended by a predetermined angle from a side of the incision groove of the support plate, having an upward/downward elastic displacement. A pair of elastic supporting units(18) supports the fixing groove of the shaft, formed at the end of the clamp member.
