| In order to improve a seizure resistance as well as restricting of a dispersion of a rotation torque, surface roughness of a large diameter side end face (4A) of a tapered roller (4) is defined as a value satisfying both the following conditional expressions (1) and (2).where, Ra(r) is a |

| The large-end-face roughness .sigma..sub.1 of the tapered roller is set to be not less than 0.04 .mu.mRa, consequently the assembling torque becomes generally constant and smaller in fluctuation over a range that the cone-back rib face roughness .sigma..sub.2 is 0.03-0.23 .mu.mRa. Also, |
