[Claims]
1. A pair of rim portions coaxially arranged with each other and a plurality of rim portions erected between the rim portions in order to evenly hold a plurality of rollers arranged between the outer ring raceway surface and the inner ring raceway surface. and a column portion, said a respective rim portion and the roller bearing cage that individually housed the respective rollers in a plurality of pockets which are defined by the column sections,
The outer peripheral surface of the pillar portion is formed with a step inward in the radial direction with respect to the outer peripheral surface of each rim portion, and a reduced surface having a smaller radius is formed at the outer end portion of the outer peripheral surface of each rim portion. and roller bearing cage, wherein the width dimension of the reduction plane is 2 or less thirds of the width of the rim portion.
2. A roller bearing in which a plurality of rollers are arranged between an outer ring raceway surface and an inner ring raceway surface so as to be rollable in the circumferential direction via a cage.
A roller bearing according to claim 1, wherein the roller bearing cage according to claim 1 is used as the cage.

[Means for solving problems]
In order to achieve the above-mentioned object, the present invention includes a pair of rim portions coaxially arranged with each other and each of the rims in order to evenly hold a plurality of rollers arranged between the outer ring raceway surface and the inner ring raceway surface. and a plurality of pillar portions which are bridged between parts, said a respective rim portion and the roller bearing cage that individually housed the respective rollers in a plurality of pockets which are defined by the column sections, The outer peripheral surface of the pillar portion is formed with a step inward in the radial direction with respect to the outer peripheral surface of each rim portion, and a reduced surface having a smaller radius is formed at the outer end portion of the outer peripheral surface of each rim portion. Moreover, the width dimension of the reduced surface is two-thirds or less of the width dimension of the rim portion.
Further, in order to achieve the above-mentioned object, the present invention is a roller bearing in which a plurality of rollers are arranged between the outer ring raceway surface and the inner ring raceway surface so as to be rollable in the circumferential direction via a cage. Therefore, as the cage, the roller bearing cage is used.

このように構成されたころ軸受保持器及びころ軸受においては、柱部の全域が外輪軌道面に対して接触しないため、従来に比較して潤滑不良が生じる虞れを低くできることになる。
また、このようなころ軸受保持器及びころ軸受においては、各リム部の外周面における外端部に縮小面が形成されているため、外輪軌道面に対して積極的に潤滑剤を案内でき、これによっても従来に比較して潤滑不良が生じる虞れを低くできることになる。
In this roller bearing cage and roller bearings configured to, because the entire column portions do not contact with the outer ring raceway surface, it becomes possible to reduce the possibility that lubrication as compared with the conventional failure occurs.
Further, in such a roller cage and roller bearing bearing, since the reduction plane to the outer end portion of the outer peripheral surface of the rim portion is formed, actively can guide the lubricant with respect to the outer ring raceway surface This also makes it possible to reduce the risk of poor lubrication as compared with the conventional case.
