A power transmission device and a combine-harvest using the power transmission device provide simplified structure and compact arrangement space. Axes of a first transmission shaft (32), a second transmission shaft (36) and a third transmission shaft (40) are arranged in a parallel way; the three transmission shafts are proximately arranged in a shape of a triangular in axial direction; the first transmission shaft (32) is in an interlocked connection with the second transmission shaft (36) via a first annular rotating body (42); the second rotating shaft (36) is in an interlocked connection with the third transmission shaft (40) via a second annular rotating body (42); a first arm of force (48) supports a first tensioning wheel (47) applying force to the first annular rotating body (38); a second arm of force (50) supports a second tensioning wheel (49) applying force to the second annular rotating body (42); and the first and the second arms of force are movably supported by the same support shaft (51). |
