Abstract
A rotation shaft coupling structure includes a roller drive shaft including a recessed portion having an internal thread; a rotation roller including a coupling member housing the recessed portion of the roller drive shaft; and a coupling shaft extending through the rotation roller in the axial direction. The coupling shaft includes a threaded portion at a first end portion thereof, the threaded portion mating with the internal thread of the recessed portion, and the coupling shaft couples the roller drive shaft and the rotation roller to each other. The first end portion of the coupling shaft in the axial direction is joined to the roller drive shaft and the rotation roller in the coupling member of the rotation roller, and a second end portion of the coupling shaft in the axial direction is a free end that allows the coupling shaft to extend and contract in the axial direction.
