PROBLEM TO BE SOLVED: To provide a thrust conical roller bearing which can reduce and save the power of a mechanism and a machine which are embedded by suppressing torque at a start and a low-speed operation.SOLUTION: In this thrust conical roller bearing, a plurality of conical rollers 3 are rollingly interposed while being aligned in a circumferential direction between mutually-opposing raceway surfaces 1a, 2a of a rotation-side raceway ring 1 and a fixed-side raceway ring 2 which oppose each other in a direction of a rotation axial core C. The rotation-side raceway ring 1 has a large flange 11 larger than the raceway surface 1a at a large diameter side. A flange part 32 in which a side face 32b being a roller face contacts with the large flange 11 is arranged at a large-diameter side end of the conical roller 3. A contact position A contacting with the large flange 11 at the side face 32b of the flange part 32 is arranged on an extension of a rolling face 3a. |
