Zusammenfassung:	PROBLEM TO BE SOLVED: To eliminate the appearance of an abnormal sound from the drive pulley of a combined harvester and thresher in case of a speed increase, without any substantial reform. SOLUTION: A drive pulley 7 is made of a stationary pulley piece 7A axially fixed and supported on a drive shaft 7C in an integrated rotation state, and a movable pulley piece 7B formed to be capable of nearing and parting from the stationary pulley piece 7A and externally coupled to the drive shaft 7C in an integrated rotation state. Also, an axial gap at the coupled part of the movable pulley piece 7B and the drive shaft 7C is formed to have a taper coupled state, as so to increase toward the opposite side of the fixed pulley 7a in the axial direction.
