ABSTRACT:
A compressor is provided with a housing having a boss portion forming a central bore through which a drive shaft is passed, and a clutch has a rotor rotatably supported by the boss portion through a ball bearing. An armature thereof has a frictional surface facing, with a small gap therebetween, a frictional surface of the rotor, and a holder plate is connected to a surface of the armature opposite that frictional surface by rivets. The holder plate has a tubular portion connected to a hub via an annular cushion rubber, and the hub is in spline engagement with the drive shaft of the compressor. An oil sleeve is oil-tightly fitted to the boss portion and axially passed through a central opening of a cover located on the surface of the armature, opposite the frictional surface thereof. The oil sleeve has at its free end an annular flange shaped oil cut portion radially faced with the cover.
