PROBLEM TO BE SOLVED: To obtain a rotating shaft support structure of a transmission which reduces a load of a conical roller bearing caused by a thrust load from a gear without employing fixation by the fastening of a nut member to the fixation of the gear which is fit to a rotating shaft, and can secure the durability of the bearing.SOLUTION: A rotating shaft support structure of a transmission comprises a reduction driven gear (driven gear) which transmits a rotation force to a drive pinion shaft (rotating shaft), and a conical roller bearing 100. The drive pinion shaft has a spline part 16, a stepping part 12a and a step part 17. A part of the conical roller bearing 100 has a split flange member 140 (split member) which is fixed to the drive pinion shaft by an integral attachment structure, and is split into two pieces in a peripheral direction, and an annular member 150 for fixing the split flange member 140. With one end face 140a (one portion of the split member) of the split flange member 140 in an axial direction as positioned in the axial direction, a main body of the conical roller bearing is fixed to the stepping part 12a of the drive pinion shaft.SELECTED DRAWING: Figure 2 |
