ABSTRACT:
An electromagnetic clutch is disposed between a drive source and a driven device for connecting and disconnecting the drive source to and from the driven device, respectively. The electromagnetic clutch includes a body rotatable by the rotative power from the drive source and an armature faced to, but normally spaced from the rotatable body. An exciting solenoid when energized moves the armature into an engaging position where the armature is attracted and urges against an end face of the rotatable body. A bearing is disposed between a fixed member of the driven device and the inner peripheral surface of the rotatable body for rotatably supporting the rotatable body on the fixed member. A cylindrical cover member is fixedly mounted, independently of the bearing, on a portion of the inner peripheral surface of the rotatable body between an axial end face thereof and the bearing. The cover member includes a peripheral wall covering a gap between the rotatable body and the armature and an annular end wall extending radially inwardly from an axial end of the peripheral wall by a considerable distance and cooperating with the peripheral wall to define a reservoir for oil and grease.
