Disclosed is a coupling structure between a drive shaft and a swash plate assembly in a variable capacity swash plate type compressor, which is so modified that the rotating force of the drive shaft can be transferred to a rotor and the swash plate assembly by substantially equal amounts so as to prevent the frictional of a driving unit as well as prolong life time. In a variable capacity swash plate type compressor which rotates the swash plate assembly, which is hingeably coupled to one side of a rotor in such a manner that its inclination angle is adjustable, under the rotating force of the drive shaft to reciprocate a piston within a cylinder bore, the coupling structure comprises: the swash plate assembly which includes a drive shaft through-hole for passage of the drive shaft, a hub having a boss with a plurality of pin holes on the outer circumferential surface thereof, and a plate coupled to the outer periphery of the boss and having the piston mounted thereon; the drive shaft which includes a plurality of slots formed thereon in an axial direction corresponding to the pin holes of the hub, the slots communicating and intersecting with each other; and a plurality of coupling pins inserted into the pin holes and the corresponding slots to couple the swash plate to the drive shaft.
