  • Patent number: 10955012
    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. The leaf spring includes a moving portion that moves in the axial direction together with the movement of the armature. The anti-vibration member is fixed to the moving portion of the leaf spring. The anti-vibration member includes a stopper that comes in contact with the flange, and a damper that comes in contact with the armature. With this configuration, an electromagnetic connecting device capable of reducing an impact sound both when the armature is attracted and released can be manufactured at a low manufacturing cost.
