<P>PROBLEM TO BE SOLVED: To provide a bearing capable of preventing vibration during an operation of the bearing without increasing cost. <P>SOLUTION: A plurality of balls 9 are annularly disposed between an inner ring 7 and an outer ring 8. Annular support recessed parts 10 for supporting the balls 9 are formed on the outer periphery of the inner ring 7, and annular support recessed parts 11 for supporting the balls 9 are formed on the inner periphery of the outer ring 8. The support recessed parts 10 and 11 have U-shaped cross section and support the balls 9. U-shaped annular grooves 12 for supporting elastic rings are formed in the support recessed parts 10 of the inner ring 7, and the elastic rings 13 such as O-rings as elastic sections are engaged with the annular grooves 12. The depth of the annular grooves 12 is shorter than the diameter of the elastic rings 13 to project the elastic rings 13 from the annular grooves 12. <P>COPYRIGHT: (C)2004,JPO |
