PROBLEM TO BE SOLVED: To provide a cutting dust-proof structure for a combine harvester that has the guide rail causing no torsion and no inclination in parallel with the threshing drum cover, even when the sliding-switch is operated in order to release the cutting and dusting cover to the handling posture. SOLUTION: The guide rail (6) that slidably switches the rear and movable dusting cover (1) in the cutting dust cover (D) to the handling posture (E) is provided above the threshing drum cover (2) and the descending groove (9) and the horizontal grooves (10) are set and connected to each other. In this case, the front roller (4) set to the rear dusting cover is made liftable, as it is faced to the descending groove (9), while the rear roller (5) is fitted to the horizontal groove (10) so that it may act as a turning fulcrum and may follow the fluctuation of the cutting lift. In the receptacle handling posture (E), the front and rear roller (4), (5) are pushed up to the horizontal groove (10) and are received, as it is inclined, so that the top edge may turn upward to the space area between the exhaustion auger (8) and the threshing drum cover (2), whereby the feed inlet is largely opened.
