PURPOSE: A rivet structure of an electromagnetic clutch for a compressor of a vehicle is provided to improve the binding force between a rivet and a damper and to reduce the weight of the rivet. CONSTITUTION: An electromagnetic clutch is equipped with a damper(8) and a rivet(20). The damper is housed in a damper case. The rivet penetrates and combines the damper, the damper case, and an armature disk. The rivet has a conjunction-reinforcing unit on the outer peripheral surface contacted with the damper and the rivet is a hollow shape. The binding force of the rivet with the damper is reinforced with forming the uneven parts(21a). Since the weight of the rivet is formed as hollow shape, the weight of the rivet is reduced.
