<P>PROBLEM TO BE SOLVED: To provide a tapered roller bearing with the reduced possibility of damage to a spacer. <P>SOLUTION: This tapered roller bearing comprises an outer ring, an inner ring, a plurality of tapered rollers so disposed between the outer ring and the inner ring as to be arranged continuously with each other in the circumferential direction, and a spacer retainer having a plurality of resin spacers 11 which are arranged between the adjacent tapered rollers and in which the intervals of the surfaces thereof in contact with the tapered rollers adjacent to each other on a roller pitch circle diameter are gradually increased from the small diameter side end faces to the large diameter side end faces of the tapered rollers. The spacers 11 are arranged separately from each other. The spacer 11 has a thick part the wall thickness of which is large and a thin part the wall thickness of which is small. A space 19 for reducing the thickness is formed in the thick part. <P>COPYRIGHT: (C)2008,JPO&INPIT |
