To simplify a transmission structure to raising devices and simultaneously enable to smoothly swing up the raising devices without being driven in the reverse direction, in a combine harvester in which two or more raising devices are parallelly and laterally arranged and disposed in the front portion of a reaping portion and supporting the raising devices in a swingable state.
In the raising driving structure of the combine harvester the raising devices 13 are gear-interlocked with a counter shaft 41 laterally spun and supported on the upper portion of the raising devices 13 in a state of swingable up on the axis X of the counter shaft 41 as a center, and a transmission interceptor is disposed in a power transmission system to the raising devices 13, wherein by the interception operation of the transmission interceptor, the transmission of a reverse driving force from the counter shaft 41 to the raising devices 13 by the swinging-up of the raising devices 13 are intercepted.
