A protective cover includes: a synthetic resin disc part having formed therein a separation wall which is thinner than other parts of the disc part and separates a magnetic encoder and a magnetic sensor from each other; and a synthetic resin sensor holder part protruding inward from the disc part. A gate mark caused by the injection molding is present n an outer peripheral surface of the disc part or an outer peripheral surface of a cylindrical part continuous with the disc part, in the radially outer side of the separation wall. Since the gate is at the radially outer side, of the separation wall, which is near the separation wall, no charging end weld is generated on the separation wall when a molten synthetic resin material is injected from the gate into the cavity of the injection mold die and solidified in an injection molding step.
