摘要： An electromagnetic clutch having a solenoid coil (80), a coil housing (81) disposed surrounding the solenoid coil (80), an armature plate (82) 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 (52). The current flowing to the solenoid coil (80) is controlled so as to control the clamping of the armature plate (82) to the coil housing (81), and the clamping force acting on the armature plate is used made to act on the clutch mechanism via a ball cam mechanism (65). 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.
