PROBLEM TO BE SOLVED: To provide the rotary bucket device of a harvester wherein a rotary rail does not slip on driving wheels, even when the rotary rail and the driving wheels are wetted with rain, etc. SOLUTION: This rotary bucket device comprises a rotary bucket 2, a rotary rail 3 which is coaxially attached to one of the end surfaces of the rotary bucket and has an channel-like outer circumferential surface, one or more driving wheels 4 which are attached to the frame of a harvester and are used for rotating the rotary rail, and one or more press rollers 5 which are attached to the frame and are rotatably brought into contact with the rotary rail to prevent its fluctuation. Therein, a toothed belt 6 or a belt having pin holes is wound and fixed to the channel-like outer circumferential surface of the rotary rail. A gear capable of being engaged with the teeth of the toothed belt, a pin wheel capable of being engaged with the pin holes of the belt having the pin holes, or an uneven wheel having mountain-like convexes and concaves on the circumferential surface is disposed as the driving wheel.
