<p>PROBLEM TO BE SOLVED: To provide an electromagnetic clutch device facilitating torque measurement of a pilot clutch structure by forming the pilot clutch structure into a module to make it attachable/detachable to/from the structure. SOLUTION: The pilot clutch structure 30 is formed in a module structure in which a pilot clutch plate group 31, an electromagnetic solenoid 33, and an armature 34 are combined in a unit. The pilot clutch plate group 31 is attachable/detachably connected to the cam input 41 of a ball cam 40, while engaging the pilot clutch structure 30 formed in a module with one of internal and external peripheral rotary members 50, 60 in the rotating direction. Torque of the pilot clutch structure 30 can be independently measured separately from the main clutch structure 20.</p> |
