PROBLEM TO BE SOLVED: To prevent vibration and noise from occurring by minimizing the wear of separators in a rolling bearing. SOLUTION: In this rolling bearing having the separators 5 and 6 installed between rolling elements 3 and 3, both the separators 5 and 6 are formed of a solid lubricant, and at least one of the separators 5 and 6 is formed so that a groove-like recessed face 5d is formed in a side face part in contact with the rolling elements 3 starting at the axial one end thereof toward at least the center part thereof. By this, since the separator 5 having the groove-like recessed face 5d can be inserted for assembly into clearances between the rolling elements 3 and 3 along the axial direction without being caught even if the clearances are small, the clearances between the rolling elements 3 and the separators 5 and 6 can be reduced. Also, a contact between the rolling elements 3 and the separator 5 is brought into a line contact or a contact similar to the line contact. COPYRIGHT: (C)2005,JPO&NCIPI
