<p><P>PROBLEM TO BE SOLVED: To surely restrict generation of drag torque in the case of shutting current supply to an electromagnetic coil of an electromagnet 62. <P>SOLUTION: In a communicating route 63a formed in an armature 63, an end opening part confronts with a base end side of an inner positive rotation direction of a pilot inner clutch plate 641 for a pilot outer clutch plate 642 among outer gap holes 642b of the pilot outer clutch plate 642 in the case of shutting current supply to the electromagnetic coil and another end opening part communicates to outer surfaces of the armature 63 except for those at the vehicle rear side. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
