Abstract
Construction of a roller thrust bearing is achieved wherein it is possible to keep a thrust race from coming apart from a cage without wear or cracking occurring in a cage element and without impact occurring between the thrust race and cage even when used in an application wherein a rotating section rotates at high speed, or when used in an application wherein relative displacement between members of a rotating section is large. The thickness of metal plate of a first cage element 35 is preferably ⅚ the thickness of metal plate of a second cage element 36 or less. Alternatively, the thickness of metal plate of a second cage element 56 is preferably ⅚ the thickness of metal plate of a first cage element 55 or less.
