Summary:To provide a tapered roller bearing which can prevent an abrupt rise of a temperature between a large end face of tapered rollers and a large flange of an inner ring when the tapered roller bearing is stopped for a long period of time, and after that, the tapered roller bearing is started.SOLUTION: A tapered roller bearing has: a large-diameter side annular part 12 extending in a peripheral direction along large end faces 11 of a plurality of tapered rollers 4; a small-diameter side annular part 13 extending in the peripheral direction along small end faces 10 of the plurality of tapered rollers 4; and a plurality of column parts 14 for connecting the large-diameter side annular part 12 and the small-diameter side annular part 13. The large-diameter side annular part 12 has a large-diameter side pocket face 16 opposing the large end face 11 of each of the tapered rollers 4, and an oil hold recess 20 which is opened while straddling a clearance between an internal peripheral face of the large-diameter side annular part 12 and the large-diameter side pocket face 16. The oil hold recess 20 is formed into a polygonal shape having two or more corner parts 21 at which adjacent inner faces of the oil holding recess 20 intersect with each other.SELECTED DRAWING: Figure 1 【課題】円すいころ軸受が長時間にわたって停止し、その後、円すいころ軸受が始動するときに、円すいころの大端面と内輪の大鍔の間に急昇温が生じるのを防止することが可能な円すいころ軸受を提供する。【解決手段】複数の円すいころ４の大端面１１に沿って周方向に延びる大径側環状部１２と、複数の円すいころ４の小端面１０に沿って周方向に延びる小径側環状部１３と、大径側環状部１２と小径側環状部１３を連結する複数の柱部１４とを有し、大径側環状部１２は、各円すいころ４の大端面１１に対向する大径側ポケット面１６と、大径側環状部１２の内周面と大径側ポケット面１６の間にまたがって開口する保油凹部２０とを有する円すいころ軸受において、保油凹部２０は、軸方向に見て、保油凹部２０の隣り合う内面同士が交わる隅角部２１を２つ以上有する多角形状に形成されている。【選択図】図１
