Abstract

PURPOSE:To positively perform the fixing of a bearing at low cost by pressing a plurality of rollers disposed separately from each other at a predetermined angle in the peripheral direction on a tip end conical part, to a shaft hole opening end after inserting the bearing into a shaft hole to form a projection inwardly at the opening end. CONSTITUTION:A needle bearing 15 is forced into a shaft hole 12 formed in a housing 11. Next, a jig 17 is disposed and prepared in opposite to an opening end 11A of the shaft hole 12. The jig 17 comprises a shaft 17A having a diameter which is greater than that of the shaft hole 12, a conical part 17B formed on the tip end portion of the shaft 17A, and a plurality of rollers 17C disposed on the conical surface separately from each other in the peripheral direction. The roller 17C is inclined at a predetermined angle with respect to an axis and disposed on the conical surface so that the diameter of the roller C becomes substantially equal to the diameter of the opening end 11A of the shaft hole 12. By pressing the roller 17C to the opening end 11A, a projection 11B which protrudes inwardly in the radial direction is formed on the opening end 11A.
