A traction roller transmission having a number of traction rollers disposed in an annular space formed between a sun roller rotatable with one shaft and traction rings surrounding the sun roller. The traction rollers are rotatably supported and mounted for movement with another shaft and the traction rings are slightly conical and held in position by cam structures such that a torque transmitted through the transmission forces the conical traction rings toward each other so as to cause firm engagement of the traction rollers with the traction rings and the sun roller. Springs are disposed between the traction rings to provide for return of the traction rings when the torque transmitted through the transmission is reduced.
