<P>PROBLEM TO BE SOLVED: To provide a rolling bearing cage for preventing the leakage of lubricant to the side face of an inner ring. <P>SOLUTION: The resin annular cage 2 is used for a rolling bearing into which rolling elements are rollingly incorporated between bearing rings for revolving between inner and outer rings in the state of rotatably holding the plurality of rolling elements one by one in pockets. On an inner periphery Sin of the cage, a cage guide portion (an inner diameter face) 10 is provided which is protruded to the outer periphery of the bearing ring opposed to the inner periphery of the cage for partially contacting the outer periphery of the bearing ring. The cage guide portion is protruded a predetermined distance L from an intersection P between an annular back face 12 and the inner periphery of the cage. On the back face of the cage guide portion, a non-contact region T is formed which does not contact the outer periphery of the bearing ring. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
