<P>PROBLEM TO BE SOLVED: To provide a radial roller bearing retainer which is excellent in all of strength, a molding property and an assembling property while achieving the energy-saving of a spring mechanism. <P>SOLUTION: Each of a pair of rims 4a, 4b forms a noncontinuous broken-ring shape having a missing part 8a, 8b every one place, and the missing parts of respective rims are arranged oppositely to each other at a predetermined interval concentrically with respect to the axial direction while forming the same phase with respect to the circumferential direction. A plurality of columns 6 form pockets 10 which hold the rollers. The pair of rims are provided with an elastic joining part 12 which is stretchable and joins one end 84a in the circumferential direction of one side rim and the other end 82b in the circumferential direction of the other side rim to each other. The other end 82a in the circumferential direction of the one side rim has a protrusion 86a which is protruded toward one end, and the one end has a recessed part 88a which is recessed corresponding to the protrusion of the other end. The one end 84b in the circumferential direction of the other side rim has a protrusion 86b protruded toward the other end, and the other end has a recessed part 88b which is recessed corresponding to the protrusion of the one end. <P>COPYRIGHT: (C)2012,JPO&INPIT |
