<P>PROBLEM TO BE SOLVED: To provide a conical roller bearing which can be improved in assembly workability and achieved in a long service life. <P>SOLUTION: The conical roller bearing comprises an inner ring 21, an outer ring 22, a conical roller 23, and a resin retainer 24. A flange 26 which protrudes to the outside-diameter side and receives the large end face of the conical roller 23 is provided at the large-diameter side of the inner ring 21, and a raceway 25 reaching the small-diameter end from the flange 26 is formed thereat. The retainer 24 comprises a resin retainer main body 34 comprising a large-diameter side annular part 24a, a small-diameter side annular part 24b, and a pillar part 24c, and an engagement part 36 which protrudes in the inside-diameter direction from the large-diameter side annular part 24a, and is engaged with the flange 26 of the inner ring 21. A recess 45 for the engagement part is provided in an engagement part corresponding position of the small-diameter side annular part 24b where an inside-diameter part 39 of the engagement part 36 corresponds as viewed from the axial direction. The recess 45 for the engagement part is provided at the outside-diameter side of the small-diameter side annular part 24b, and is formed by a notch 47 opening to the outside-diameter side. <P>COPYRIGHT: (C)2009,JPO&INPIT |
