Abstract
A magnetic clutch device having improved durability and reliability without increasing a size in an axial direction. A fixed member, the first engagement element, and a second engagement element are arranged concentrically to one another in order from a rotational center axis. The first engagement element comprises a first magnet. The fixed member comprises a second magnet in which a polarity is switched between a straight polarity and a reversed polarity, and a coil that switches the polarity of the second magnet depending on a direction of the current applied thereto.
