An electromagnetic clutch having a solenoid coil ( ), a coil housing ( ) disposed surrounding the solenoid coil ( ), an armature plate ( ) disposed facing the side of the coil housing, and a wet-type multi-plate clutch mechanism, the armature plate being linked to the clutch housing ( ). The current flowing to the solenoid coil ( ) is controlled so as to control the clamping of the armature plate ( ) to the coil housing ( ), and the clamping force acting on the armature plate is used made to act on the clutch mechanism via a ball cam mechanism ( ). A first rotational backlash amount BLm occurring between the rotation input member and the rotation output member in a rotation transmission system in which the clutch mechanism is interposed in an engaged state, and a second rotational backlash amount BLp occurring between the rotation input member and the rotation output member in a rotation transmission system in which the cam mechanism is interposed in a state in which the cam mechanism is fixed and the armature plate is clamped to the coil housing, are set such that BLm>BLp.
