ABSTRACT:
In an electromagnetic clutch, an annular exciting coil having a pair of connecting portions at its intermediate winding portion, a coil bobbin, having a first coil holding groove for holding the exciting coil, and a coil cover, having a second coil holding groove for holding the exciting coil projecting from the coil bobbin, are stored in a yoke to expose a storing portion formed on the coil cover and having a pair of through holes from which the connecting portions of the exciting coil are led out. A temperature fuse is stored in the storing portion and has a pair of lead wires. A pair of intermediate terminals are arranged to oppose each other through a predetermined distance, and have lead press-insertion grooves where the lead wires of the temperature fuse are to be press-inserted, and coil press-insertion grooves where the connecting portions of the exciting coil led out from the through holes are to be press-inserted. A terminal cover fixes the intermediate terminals. A rotor has an annular groove for storing the yoke, and a first friction surface formed by a side surface opposite to the annular groove. An armature has a second friction surface to be magnetically attracted by the first friction surface.
