PROBLEM TO BE SOLVED: To provide a magnetic clutch mechanism which has excellent durability and excellent reliability, and the dimension of which can be suppressed from increasing in the rotation center axis direction.SOLUTION: A first engagement element 22 and a second engagement element 23 are coaxially disposed. A fixed body 21 that does not rotate is disposed concentrically with the first engagement element 22 and the second engagement element 23, and is disposed on the inner circumferential side or outer circumferential side of the first engagement element 22 and the second engagement element 23. The first engagement element 22 adjacent, in a concentric radial direction, to the fixed body 21, has a first permanent magnet 27. The fixed body 21 has a second permanent magnet 25 that is switched between a positive polarity following the direction of a magnetic path formed between the fixed body 21 and the first engagement element 22 by the first permanent magnet 27, and a reverse polarity opposite to the direction of the magnetic path, and has a coil 26 for generating a magnetic field which inverts the polarity of the second permanent magnet 25 according to the direction of current.SELECTED DRAWING: Figure 2

    【課題】耐久性や信頼性に優れ、かつ回転中心軸線方向への寸法の増大を抑制することのできる磁気クラッチ機構を提供する。【解決手段】第1係合要素22と第2係合要素23とが同心円上に配置され、回転することのない固定体21が、第1係合要素22および第2係合要素23に対して同心円上でかつ第1係合要素22および第2係合要素23に対して内周側もしくは外周側に配置され、固定体21に同心円上の半径方向で隣接する第1係合要素22は、第1永久磁石27を有し、固定体21は、第1永久磁石27によって固定体21と第1係合要素22との間に形成される磁路の方向に準じた正極性と磁路の方向とは反対の逆極性とに切り替わる第2永久磁石25と、電流の方向に応じて第2永久磁石25の極性を反転させる磁界を発生するコイル26とを有する。【選択図】図2
