Disclosed is a drive mechanism for a single facer having a first fluted roll unit consisting of a pair of outer and inner fluted rolls, a second fluted roll unit also consisting of a pair of outer and inner fluted rolls, and a press roll, wherein the press roll is designed to be operated selectively in combination with the first fluted roll unit or with the second fluted roll unit; characterized in that the drive mechanism comprises: a drive gear to be rotated by a suitable drive means fixed upon a drive shaft which is drivingly connected to a rotary shaft of the press roll in such a way that the drive shaft may be rotated integrally with the rotary shaft; a driven gear mounted upon a driven shaft which is connected to the rotary shaft of the outer or inner fluted roll in each of the first and second fluted roll units, to be integrally rotatable with the rotary shaft, the driven gear being freely rotatable upon the driven shaft under engagement with the drive gear; a clutch for achieving ON/OFF shifting of power transmission from the driven gear to the driven shaft; and a power transmitting member disposed upon the driven shaft with a one-way clutch, which is rotated by an idling drive means when the former clutch is released.
