PROBLEM TO BE SOLVED: To provide a compact endless belt conveyor without requiring time and effort to adjust a position for taking crops even when a tension is given to the endless belt end. SOLUTION: The endless belt conveyor is an upper transport device 60 equipped with a chain 61 attached with a plurality of tines 61a to be protrudable in a predetermined interval on the outer periphery and brings a side for transporting reaped cereal stems 99 by action of the protruded tines 61a to be an action side and a side opposite to the action side to be a non-action side. The device 60 is equipped with a guide rail 67 for guiding the chain 61 in the non-action side and movable in the action side direction and a pulling spring 73 for forcing the guide rail 67 in order to move toward the action side. The guide rail 67 moves toward the direction of the action side by actuating force of the pulling spring 73 to add tension to the chain 61. COPYRIGHT: (C)2009,JPO&INPIT
