In the first layer part 31, because the fibers 31a are oriented so as to extend in the circumferential direction of the cylindrical member 16, the fibers 31a of the first layer part 31 are made less likely to be caught by a permanent magnet 17 when the permanent magnet 17 is press-fitted inside the inner peripheral surface 16a of the cylindrical member 16, and a portion of the inner peripheral surface 16a of the cylindrical member 16, inside which a first shaft member or a second shaft member is press-fitted is hindered from being scraped by the permanent magnet 17. In addition, the cylindrical member 16 is composed by at least layering a second layer part 32 in which fibers 32a are oriented so as to extend in the axial direction of the cylindrical member 16.
