[Means for Resolution] A magnetized body is a bonded magnet and is fixed to a support member by integral injection molding. A bend portion extending axially outwardly is formed in an outwardly-directed flange portion of the support member. A come-off preventing concave portion is constituted by the bend portion and the outwardly-directed flange portion. The magnetized body enters this concave portion. Consequently, the magnetized body is prevented from performing relative movement with respect to the support member.
