PROBLEM TO BE SOLVED: To provide a combine harvester so designed that, in making a switching operation of a narrow guide between a working mode and a housing mode from the combine harvesters steering seat, the transmission of operating power by a relevant operating wire can be made accurate to improve the switching operability, and the operating wires durability is improved through eliminating repeating the extension and slacking of the operating wire.SOLUTION: The combine harvester has the following scheme: a reaping conveying apparatus (3) is set up in a transversely slidable way in the front of a traveling vehicle body (2) having a steering seat (1), and connected to the traveling vehicle body (2) side via a transmission unit (4) movable transversely following the transversely sliding motion. An operating wire (6) functioning to make a switching operation of a narrow guide (5) provided on the flank of the reaping conveying apparatus (3) between a working mode and a housing mode from the combine harvesters steering seat (1) is set up along the transmission unit (4).COPYRIGHT: (C)2010,JPO&INPIT【課題】運転席からナローガイドを作業姿勢と格納姿勢とに切換え操作するにあたり、操作ワイヤーによる操作力の伝達を正確に行えるものとして操作性を向上させると共に、操作ワイヤーが伸びたり緩んだりを繰り返すことをなくして耐久性を向上させる。【解決手段】運転席(1)を有する走行車体(2)の前部に、刈取搬送装置(3)を左右スライド可能に設け、刈取搬送装置(3)を、その左右スライドに追従して左右に移動できる伝動装置(4)を介して走行車体(2)側に接続し、刈取搬送装置(3)の側部に設けたナローガイド(5)を運転席(1)から作業姿勢と格納姿勢とに切換え操作する操作ワイヤー(6)を、伝動装置(4)に沿わせて設ける。【選択図】 図1
