Abstract:
A steering column has an overall hollow and cylindrical shape at least part of which is formed using a column member. The column member includes a main body portion having one-side end section and the other-side end section and a cylindrical member having one-side end section and the other-side section. The cylindrical member is joined in the axial direction with respect to the main body portion by fitting and fastening the other-side end section of the cylindrical member inside the one-side end section of the main body portion. The inner diameter of the end surface of the other-side end section of the cylindrical member is smaller than the inner diameter of a portion of the other-side end section of the cylindrical member. The portion of the other end section of the cylindrical member constitutes a joined section between the main body and the cylindrical member.
