PROBLEM TO BE SOLVED: To make a torque limiter for a harvesting part to be installed in a state easy in adjustment and inspection work and in a state easily avoiding twining of crops with a simple structure.SOLUTION: An input shaft 164 of a harvesting part 36 is arranged behind a harvesting part frame 42 in the machine body lateral direction and freely rotatably supported on a sending part frame 37a. A transmission mechanism 163b transmitting power to the harvesting part 36 is arranged at the rear side of a lateral one side part of a harvesting part frame 42 projecting from the sending part frame 37a to the lateral outside, in a state interlocking with the end part positioned at the lateral outside of the sending part frame 37a of the input shaft 164. A torque limiter 172 is arranged from an interlocking element 171 to the end part of the input shaft 164, in which the interlocking element 171 is arranged on the transmission mechanism 163b to interlock the transmission mechanism 163b with the input shaft 164.COPYRIGHT: (C)2013,JPO&INPIT【課題】収穫部用のトルクリミッタを調整や点検作業が容易な状態で、かつ作物の絡み付きを構造簡単に回避しやすい状態で装備できるようにする。【解決手段】収穫部36の入力軸164を収穫部フレーム42の背後に機体横向きに配置して送出部フレーム42に回転自在に支持してある。送出部フレーム37aから横外側に突出している収穫部フレーム42の横一側部の後方に、収穫部36に動力伝達する伝動機構163bを入力軸164のうちの送出部フレーム37aの横外側に位置する端部に連動する状態で設けてある。伝動機構163bと入力軸164とを連動させるように伝動機構163bに備えさせた連動部材171と入力軸164の端部とにわたってトルクリミッタ172を設けてある。【選択図】図12
