Abstract

A position of a second permanent magnet with respect to a first permanent magnet is defined by assembling a driving side support member, a thrust bearing, a spacing member, a radial bearing, and a driven side support member. The first and second permanent magnets are respectively held on the driving side support member and the driven side support member. Accordingly, variation of a magnetic gap between the first and second permanent magnets can be reduced. Variations in assembling the parts hardly affect the variation of the magnetic gap.
