Claims

[Scope of utility model registration request]

(1) A rotor, two magnetic shielding slits provided on the inner and outer peripheries of the friction surface of the rotor, which are arranged opposite to each other with a gap in the axial direction of the friction surface of the rotor, and are movable in the axial direction. an armature, a magnetic isolation slit provided on the armature and placed between the two slits of the rotor, a plate that fixes the armature via a leaf spring and is integrated with a boss, and a plate that connects the rotor and the armature. An electromagnetic coupling device comprising an excitation coil for pressure contact, characterized in that the shortest distance between the slit portion of the armature and the plate is set to be equal to or larger than the width of the slit of the armature.

(2) The electromagnetic coupling device according to claim 1, wherein the outer diameter of the freighter is smaller than the diameter of the slit of the armature.

(3) The electromagnetic coupling device according to claim 1, wherein the gap between the plate and the armature is equal to or greater than the slit width of the armature.
