ABSTRACT:
In a press fit arrangement of a tubular nut member in an enlarged end portion of a hollow shaft, typically used in an electric power steering device, a region of loose fit is provided in a part of an interface between the tubular nut member and the enlarged portion, adjacent to an annular shoulder defined at the inner boundary of the enlarged portion. The region of loose fit can be achieved by provided an annular recess in the inner bore of the enlarged portion and/or the outer circumferential surface of the nut member. Thereby, the region of a relatively high rigidity, which is created by the provision of the annular shoulder, is prevented from being involved in the press fit when the nut member is fitted into the inner bore of the enlarged portion until the inner end of the nut member abuts the annular shoulder so that a relatively uniform tight fit can be achieved between the nut member and the enlarged portion over a relatively large axial length. Thus, a desired tight fit can be achieved without requiring any undue press fitting pressure or without causing any undue deformation to the nut member.
