PROBLEM TO BE SOLVED: To ensure that when a magnet is secured by bonding to a cylindrical magnet holder which is secured to a first shaft, fixation by this bonding is reliable.SOLUTION: In a magnet holder 22 there is integrally provided a flange part 22a projecting outward in the radial direction from one end of the magnet holder 22 so as to come in contact with one end of a magnet 23 that is bonded to the outer circumference of the magnet holder 22. A positioning projection 23a projected at one end of the magnet 23 is engaged with a positioning recess 24 formed in the flange part 22a, and a cut-and-raise piece is formed in the magnet holder 22 that can come in contact with the other end of the magnet 23 from a side opposite to the flange part 22a.SELECTED DRAWING: Figure 3 |
