PROBLEM TO BE SOLVED: To restrain deterioration of a cylindrical roller bearing arranged between a case and a carrier.SOLUTION: An inner race 46 has a tapered outer periphery 46b, and is fixed to a carrier 10. An outer race 40 has a tapered inner periphery 40b opposed to the outer periphery 46b of the inner race 46, and is fixed to a case 4. Plural rollers 42 are arranged between the inner race 46 and the outer race 40. A retainer 44 maintains an interval between the adjacent rollers 42. An end 44d of the retainer 44 with a larger diameter comes into contact with the case 4. An end 44e of the retainer 44 with a larger diameter comes into contact with the case 4 via a second member 50. The retainer 44 comes into contact with the case 4 and the carrier 10 via the first member 52 and the second member 50, and therefore, friction can be made smaller than when the retainer comes into direct contact with the case 4 and the carrier 10. |
