Abstract: An electromagnetic connecting device includes a flange of a hub, an armature supported by the flange via a leaf spring, a rotor accommodating an electromagnetic coil, and an anti-vibration member. When an electric current is supplied to the electromagnetic coil, the armature moves in the axial direction of the hub against the spring force of the leaf spring, and is attracted to the rotor.
