PROBLEM TO BE SOLVED: To provide a facsimile machine that prevents a rocking gear from coming off even when a drive system is locked due to paper jamming or the like. SOLUTION: Rocking plates 5, 10 are made of a synthetic resin and rocking gears 4, 9 have mount holes 4a, 9a, respectively. Each of snap fit members 18, 19 comprises a fit base with a small diameter and a fit tip with a large diameter, and this fit tip is almost formed to be conical where the outer diameter is gradually increased toward the rear end from its tip. Each of the snap fit members 18, 19 had a hole, a maximum outer diameter B in the case of applying a pressure to the fit tip externally inward to deform the fit tip in a way of smashing the hole is a little larger than a diameter A of the mount holes 4a, 9a of the rocking gears 4, 9. Press-fitting the snap fit members 18, 19, respectively to the mount holes 4a, 9a support the rocking gears 4, 9 with the snap fit members 18, 19.
