A protective cover is molded through injection molding of a synthetic resin and includes a disc part, a sensor holder part protruding inward from the disc part, and a protruding part protruding inward from the disc part and being continuous with the sensor holder part. The disc part includes a separation wall which is thinner than other portions of the disc part and separates a magnetic encoder and a magnetic sensor from each other. The protruding part has, at the inward-side face thereof, a gate mark caused by the injection molding. The protruding part is provided with, at the outward-side face thereof, a thickness reduction part extending inward so as to be close to the gate mark.
