<p>PROBLEM TO BE SOLVED: To take out a lead wire of an electromagnet directly from a core to the outside of a casing. SOLUTION: This coupling is provided with a main clutch 49 disposed between torque transmission members 45, 47; an electromagnet 61 for moving an armature 59 from the outside of the torque transmission member 45; a control clutch 51 connected being pressed by the armature 59; and a cam 55 actuated receiving transmission torque between the members 45, 47 when the clutch 51 is connected, to connect the clutch 49. A core 83 of the electromagnet 61 is fixed to an opening 79 of a casing 37, and its lead wire 123 is directly led out of the casing 37.</p> |
