A coupling apparatus to transfer a rotation force in a connected state. The apparatus has a first coupler having a first sloping rib formed at one end thereof and sloped in a rotation direction, and a second coupler having a second sloping rib formed at an inner circumference of the second coupler and sloped to correspond to the first sloping rib. The sloping ribs are connected by being pressed as the first coupler and the second coupler are relatively rotated, and rotation axes of the couplers coincide when the sloping ribs are completely connected.
