An adjusting screwhas an insertion shaft portionthat mates with the insertion cylindrical portion of the shaft, and a screw-side engagement portionthat engages with the shaft-side engagement portion. The insertion shaft portion of the adjusting screw has an irregular portiona that is press-fit into the insertion cylindrical portion of the shaft, and that restricts movement in the axial direction with respect to the shaft.
