<p>An object of the present invention is to prevent breakup of segments which constitute a split type retainer for a tapered roller bearing, when the tapered roller bearing is being mounted on target equipment, thereby improving operability in the mounting process. A segment 27 for a tapered roller bearing is provided with a predetermined number of posts 31 between a small-diameter-side end fringe 28 which constitutes a small-diameter-side circumferential edge of a split type retainer 16 and a large-diameter-side end fringe 29 which constitutes a large-diameter-side circumferential edge thereof. Pockets 32 are formed between the posts 31. At least the large-diameter-side end fringe 29, out of the small-diameter-side end fringe 28 and the large-diameter-side end fringe 29, is provided with a large-diameter-side engagement piece 36. When the bearing is mounted, the large-diameter-side engagement piece 36 is engaged with the large-diameter engagement member 23 fitted and fixed onto the bearing's inner ring, whereby the segment 27 is prevented from breaking up.</p> |
