PROBLEM TO BE SOLVED: To facilitate forming a holding surface by simplifying the shape of the holding surface, in a bearing holding structure for holding a bearing having a generally spherical shape in the outer peripheral by each holding surface of a bearing holding portion formed across two members. SOLUTION: Each of holding surfaces 5c, 6c provided on bearing holding portions 5a, 6a of an end frame 5 and a holding plate 6 to hold a bearing 7 is formed in a taper shape linearly expanding toward the other member side. |
