PROBLEM TO BE SOLVED: To provide a rolling bearing capable of reducing bearing pressure of a rolling element held near an end part in the peripheral direction of cage constituting parts, in the rolling bearing for holding the rolling element at a predetermined interval in the peripheral direction by a rolling element holding part arranged in the cage constituting parts, by constituting a cage for holding the rolling element out of a plurality of cage constituting parts arranged in a different position in the peripheral direction. SOLUTION: This rolling bearing 1 includes an outer ring 2b, a plurality of first rolling elements 3 arranged in the peripheral direction of the outer ring in a space between the outer ring and a rotary shaft 2a inside of the outer ring, and the cage 5 holding the first rolling elements, and is provided by constituting the cage of the plurality of cage constituting parts 51 and 52 arranged in the different position in the peripheral direction, and is formed for holding the first rolling element at the predetermined interval in the peripheral direction by a rolling element holding part arranged between both end parts in the peripheral direction in the cage constituting parts. A second rolling element 30 is arranged between the adjacent cage constituting parts in the peripheral direction among the plurality of cage constituting parts. COPYRIGHT: (C)2009,JPO&INPIT |
