Abstract
A pair of disk-shaped annular flanges is made of material firmer than that of a hollow cylindrical-shaped roller portion. The roller portion has an outer peripheral surface in which the flanges are mounted at opposite ends thereof. On press-fitting a pair of bearings in the roller portion, the flanges are retained by means of bearing flanges. The outer peripheral surface of the roller portion has a pair of flange guides, at opposite ends thereof, for guiding the flanges. The flange guide has a longitudinal length shorter than thickness of the flange. An adhesive agent may be filled in a gap formed among an end surface of the roller portion, the disk-shaped annular flange, and the bearing.
