It is an object of the invention to maintain appropriate accuracy of a cylindrical inner peripheral face of a bearing member, which functions as a bearing surface, without using a holding jig such as a cored bar, in a case where the bearing member is passed through a mounting hole and fitted to the mounting hole by swaging. The bearing member 42 includes the large-diameter tubular portion 44 and the small-diameter tubular portion 46 both having the first cylindrical inner peripheral face 52 that functions as a bearing surface are formed, and the thin-wall tubular portion 48 having the second cylindrical outer peripheral face 54 and the second cylindrical inner peripheral face 56 with a diameter larger than that of the first cylindrical inner peripheral face 52. When the thin-wall tubular portion 48 is swaged in the axial direction, the bearing member 42 is fixedly fitted to the mounting hole 34h such that the peripheral portion of the mounting hole 34h is held. In that case, even if the second cylindrical inner peripheral face 56 of the thin-wall tubular portion 48 bulges radially inward by swaging, the bearing performance will not be affected unless the second cylindrical inner peripheral face 56 becomes smaller in diameter than the first cylindrical inner peripheral face 52 that functions as a bearing surface. Therefore, accuracy of the first cylindrical inner peripheral face 52 is appropriately maintained without using any holding jig such as a cored bar.
