Abstract
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 clutch mechanism. 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 to control the engagement of the clutch mechanism. There is also a lubricating oil supply channel ( ) for supplying lubricating oil from the inside in the radial direction into a gap between the coil housing and the armature plate, and oil reservoir holding lubricating oil to be supplied into the gap is formed around the inner periphery of the portion where the coil housing faces the armature plate.
