PROBLEM TO BE SOLVED: To provide a magnetic gear device capable of surely isolating two input-side and output-side areas without using an annular packing.SOLUTION: A magnetic gear device 1 includes an outer gear 5, an inner gear 6, a first rotational shaft 3, a second rotational shaft 4, and a case 2. The outer gear 5 comprises an outside cylinder 31 and a plurality of outside magnet pieces 32 attached to an inner peripheral part of the outside cylinder 31. The inner gear 6 comprises an inside cylinder 41 arranged on a cylinder hole of the outer gear 5 and a plurality of inside magnet pieces 42 attached to an outer peripheral part of the inside cylinder 41. The first rotational shaft 3 is connected to the inside cylinder 41 and the second rotational shaft 4 is connected to the outside cylinder 31. The case 2 isolates and partitions a first storage chamber 18 in which the inner gear 6 is arranged and a second storage chamber 19 in which the outer gear 5 is arranged. The case 2 includes a stator part 13 arranged between the inside magnet pieces 42 and the outside magnet pieces 32. |
