PROBLEM TO BE SOLVED: To provide a protection cover having a sensor holder portion of high reliability, capable of preventing degradation of airtightness and degradation of strength of a partitioning wall between a magnetic sensor and a magnetic encoder.SOLUTION: A protection cover 1 has a sensor holder portion 3B press-fitted to an outer ring to seal one end portion in an axial direction of a bearing and holding a magnetic sensor A in a bearing device including the bearing having an inner ring, the outer ring, and rolling elements rolling between the inner ring and the outer ring, a magnetic encoder positioned at one end portion in an axial direction, of the bearing and fixed to the inner ring, and the magnetic sensor A opposed to a magnetic pole of the magnetic encoder to detect rotation of the magnetic encoder. The protection cover is composed of a removal processing portion 9 configured by removing and processing at least one of a resin face 5 and a back face 6 of a partitioning wall C formed by the resin face 5 opposed to the magnetic sensor A in a state of holding the magnetic sensor A and the back face 6.SELECTED DRAWING: Figure 2
