<p>PROBLEM TO BE SOLVED: To reduce attracting sounds produced when an armature plate is attracted. SOLUTION: This electromagnetic clutch 1 is mounted to a rotation shaft 2 and has a hub 10 having a flange part 11, an armature plate 30 attracted by a rotor 20 when excited, and a plurality of spring members 40 disposed between the flange part 11 of the hub 10 and the armature plate 30 along the peripheral direction of the rotor 20. The armature plate 30 has a first annular plate 30a opposed to the rotor 20 in the axial direction with a predetermined gap, a second annular plate 30b opposed to the first plate 30a in the axial direction and connected to the first plate 30a with a predetermined gap, and an elastic body held between the first plate 30a and the second plate 30b.</p> |
