Abstract:
To provide a structure of a bearing in which a bolt is fitted on a flange of a hub shaft in a proper position at a low cost.
On a bolt bearing surface formed on the flange 21 of the hub shaft 21, the angle of inclination α of a bolt relative to a line S perpendicular to the axis P of the hub shaft is kept at 0.48 degrees or less by making the bearing surface only by forging without machining. This makes it possible to fit the bolt 10 in a through-hole 24 in the flange 21 in a proper position and reduce the manufacturing cost of the bearing.
