MAGNETIZED PULSAR RING AND ROLLING BEARING UNIT WITH SENSOR EQUIPPED THEREWITH

摘要

A magnetized body being a bonded magnet is fixed to a support member by monoblock injection molding. The support member at its outward flange part is provided with a bent part extending outward in the axial direction. A recessed portion for detachment prevention is formed by the bent part and the outward flange part. Any relative movement of the magnetized body to the support member is prevented by entry of the magnetized body in the recessed portion.
