<p><P>PROBLEM TO BE SOLVED: To provide a electromagnetic clutch device which is made compact. <P>SOLUTION: The electromagnetic clutch device comprises: a first rotor 31 provided in a casing 10 and adapted to be driven by a driving motor; a second rotor 34 having an electromagnetic coil 32 and reciprocatingly rotatable coaxially with the first rotor 31 in the direction of positive and reverse rotation at a predetermined speed for attracting the first rotor 31 with magnetic force generated by the electromagnetic coil 32; a recessed part 33 provided around the axial center of the second rotor 34; and a conductor 35 spirally arranged in the recessed part 33 around the axial center for feeding power to the electromagnetic coil 32. The conductor 35 has one end taken out of the recessed part 33 along the inner wall of the recessed part 33 in the direction of the axial center and connected to the electromagnetic coil 32 on the side of the second rotor 34 and the other end taken out of the axial center or its vicinity and located on the side of the casing 10. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
