A clutch assembly structure for a multiple disk clutch is provided which includes a first clutch assembly and a second clutch assembly which are coaxially arranged in parallel with each other, such that the first clutch assembly is located radially outwardly of the second clutch assembly. The second clutch assembly includes a second drum, a second piston slidably received in the second drum, and a second oil chamber formed between the second drum and the second piston. A canceling oil chamber for canceling the centrifugal oil pressure in the second oil chamber is formed within the second piston. In the canceling oil chamber is provided a canceling piston for canceling the centrifugal oil pressure in the second oil chamber. A second return spring consisting of a wave spring is provided between the second piston and the canceling piston. The axial length of the clutch assembly is reduced, thereby rendering the whole multiple disk clutch small-sized.
