Magnetic transmission

A magnetic transmission comprising:

• an inner magnet array where a plurality of magnetic pole pairs are disposed at substantially equal intervals along a circumferential direction;
• an outer magnet array where a plurality of magnetic pole pairs are disposed along the circumferential direction coaxially with the inner magnet array at different pitches from the magnetic pole pairs of the inner magnet array;
• and a magnetic body array coaxially disposed between the inner magnet array and the outer magnet array and where a plurality of magnetic bodies are disposed along the circumferential direction,
• wherein the inner magnet array or the outer magnet array is provided with
• a first magnet array and a second magnet array arranged in a direction of a central axis and disposed at different pitches in the circumferential direction,
• the magnetic body array is provided with
• a first magnetic body array and a second magnetic body array opposing the first magnet array and the second magnet array in a radial direction, respectively, and disposed at different pitches in the circumferential direction, and
• the inner magnet array, the outer magnet array and the magnetic body array are relatively and continuously movable in the direction of the central axis while an opposing relationship is held between the first magnetic body array and the second magnetic body array, and the first magnet array and the second magnet array.
