A disk coupling is provided to improve cushioning against the effects of shocks and vibrations and achieve a large torque transmission by manufacturing the disk coupling with a rubber material with flexibility, so that the disk coupling can be employed as a torque transmission device of a diesel engine. A disk coupling(10) for torque transmission between a drive shaft and a driven shaft, comprises outer and inner flanges(30,31), and a rubber disk(32). The outer and inner flanges, each shaped as a ring with different diameter, have a connecting hole(35) in regular intervals along the circumference respectively. The rubber disk is inserted between an inner periphery of the outer flange and an outer periphery of the inner flange, so that the inner and outer flanges are placed on a concentric circle. The rubber disk comprises a high-hardness rubber disk(33) and a low-hardness rubber disk(34) that are integrated with each other, wherein the low-hardness rubber disk is made by filling rubber between the inner flange and the high-hardness rubber disk, with the inner flange and high-hardness rubber disk are placed on the concentric circle.
