Document Type and Number:
WIPO Patent Application WO/2018/092906
Kind Code:
A1
Abstract:
A magnetic power transmission structure according to one aspect of the present invention is equipped with: a cylindrical member configured from multiple magnets arranged in a divided manner around a shaft, and multiple magnetic pole members arranged on the inside in the radial direction, in correspondence with the magnets; and a shaft member inserted into a hollow portion of the cylindrical member. The multiple magnets include magnets for which the inside in the radial direction is the N pole and magnets for which the inside in the radial direction is the S pole, and protruding parts that conform to a different helix in accordance with the magnet being magnetized are provided on the radial inside surface of each magnetic pole member. Protrusions having a helical shape in accordance with the helices are provided on the outer circumferential surface of the shaft member.
