PURPOSE:To obtain a compact shaft support part and at the same time to prevent a play caused by an operation by fitting a U-shaped part internally and externally for plural pairs of operation levers having a shaft support part at each base part and putting a shaft through each shaft hole for rotatable bearing. CONSTITUTION:A threshing clutch lever 6 is made by forming a plate matter into a U-shaped and has shaft support parts 5 containing shaft holes 3 and 4 as the base parts at the left and right side parts of the plate matter. A reaping clutch lever 7 of the same structure as the lever 6 has its U-shaped part fitted into the U-shaped part of the lever 6. Then the lever 7 is folded toward a seat 17 at its middle part and then folded again toward the lever 6 to be set in parallel to the lever 6. The upper part of the lever 7 is extended to the upper part over a lever guide groove 15a. When both threshing and reaping parts are driven, levers 6 and 7 are turned to turn the part 5 around a shaft 8. Therefore arms 19 and 21 are actuated to turn on both threshing and reaping clutches. The levers 6 and 7 are turned in the opposite direction to switch off the power. |
