っていた。In the orthogonal rolling frictional transfer device of the prior art, the pressure contact surfaces of the small taper roller 105 and the large taper roller 110 are relatively fixed in position and are inflexible. Error on the taper processing, the squareness error in the axial direction of the large taper roller 110 at the time of assembly, or the change in the taper due to the bending of the shaft causes a strong one-sided contact (per edge), resulting in partial wear on the rolling surface of the taper roller. It was a cause of damage such as flaking.

角度を調整できる。As described above, according to the present invention, at least one of the small diameter taper roller and the large diameter taper roller is provided with the elasticity imparting portion for imparting elasticity to the tapered surface portion. The following effects can be obtained. (1) Since the taper surfaces of the small-diameter taper roller and the large-diameter taper roller do not hit against each other stably, and smooth power transmission is performed, durability is significantly improved. In addition, the rotation accuracy level including rotation unevenness is improved. (2) Since there is no extra rotating portion, power loss is reduced and transmission efficiency is improved. (3) Since the number of parts is small and the processing precision of the taper of the taper roller can be loosened, the cost is reduced. (4) Due to the action of the pressure contact force, the taper surfaces of both taper rollers are easily aligned with each other, so that the number of assembling steps can be reduced. (5) With the adjustment nut for finely adjusting the taper angle of the large taper roller, the angle of the large taper roller can be adjusted by a simple adjustment operation.
