PROBLEM TO BE SOLVED: To provide a thermomagnetic cycle device capable of realizing a high coefficient of performance.SOLUTION: A thermomagnetic cycle device forms first and second transverse flow passages extending between an element bed and a piston 41 that is one of distributing devices for thermal transfer medium relatively rotational moving in respect to the element bed. The thermomagnetic cycle device has an inner leakage restricting mechanism 19 acting as a part of configuration of a flow passage changing-over mechanism. The inner leakage restricting mechanism 19 restricts an inner leakage between the first and second transverse flow passages in reference to a relative positional relation among first openings 41a1, 41b1 of the piston 41 in the first traverse flow passage and second openings 41c1, 41d1 of the piston 41 in the second transverse flow passage.SELECTED DRAWING: Figure 12 【課題】高い成績係数を実現することが可能な熱磁気サイクル装置を提供すること。【解決手段】熱磁気サイクル装置は、素子ベッドと素子ベッドに対して相対的回転移動する熱輸送媒体の分配装置の１つであるピストン４１との間に渡って延びる第１、第２横断流路を形成する。熱磁気サイクル装置は流路切換機構の構成の一部として内部リーク抑制機構１９を備える。内部リーク抑制機構１９は、第１横断流路内のピストン４１の第１開口４１ａ１、４１ｂ１と、第２横断流路内のピストン４１の第２開口４１ｃ１、４１ｄ１との相互の位置関係により、第１、第２横断流路間の内部リークを抑制する。【選択図】図１２
