特開２０００−９２９６２号公報（段落〔００２５〕、〔００２６〕、図１，２，３）JP 2000-92962 A (paragraphs [0025], [0026], FIGS. 1, 2 and 3)

上記した収穫機において、操縦塔を機体後方側に寄せるほど、走行機体の前後長さが小になり、収穫機全体の前後長さを短くすることができる。この場合、運転座席と操縦塔との間隔が狭くなり、上記した従来の運転部構造に関する技術を採用したものにあっては、運転部の居住性あるいは操向操作具の操作性での問題が発生しやすくなっていた。   In the harvester described above, the front-rear length of the traveling machine body becomes smaller as the control tower is moved closer to the rear side of the machine body, and the front-rear length of the entire harvester machine can be shortened. In this case, the distance between the driver's seat and the control tower becomes narrow, and in the case of adopting the above-described conventional technology relating to the driving unit structure, there is a problem in the comfort of the driving unit or the operability of the steering operation tool. It was easy to occur.

つまり、上記した従来の技術を採用すると、操縦塔の操向操作具が突出する部位での上面と、この部位の横側に位置する部位での上面とが同一の配置高さに位置する。
運転座席と操縦塔との間隔が狭くても、ひざがしらが操縦塔の上方に出た体勢で楽に着座することができるよう、操縦塔の上面の配置高さを低くすると、操縦塔の操向操作具が突出する部位での上面の配置高さも低くなる。操向操作具の揺れ動きが発生しにくいよう、あるいは操向操作具の揺動ストロークが大きくなり過ぎないよう、操向操作具の操縦塔上面からの突出長さを抑制すると、操向操作具の配置高さが低くなり、操向操作具を操作しにくくなる。
操向操作具の操縦塔上面からの突出長さを抑制しながら操向操作具の操作が容易になるようにするには、操縦塔の操向操作具が突出する部位での上面の配置高さを高くする必要がある。すると、操縦塔の操向操作具が突出する部位の横側に位置する部位での上面の配置高さも高くなって、ひざがしらを操縦塔の上方に出しにくくなり、脚を操縦塔の後側に収めた窮屈な体勢で着座せねばならない。 That is, when the above-described conventional technique is employed, the upper surface at the portion where the steering operation tool of the control tower protrudes and the upper surface at the portion located on the lateral side of this portion are positioned at the same arrangement height.
Even if the distance between the driver's seat and the control tower is small, the height of the upper surface of the control tower can be reduced so that the knee can sit comfortably in the position above the control tower. The arrangement height of the upper surface at the portion where the direction operation tool protrudes also becomes low. If the protruding length of the steering control tool from the top of the control tower is suppressed so that the steering control tool does not easily swing or the swing stroke of the steering control tool does not become too large, the steering control tool The arrangement height becomes low, and it becomes difficult to operate the steering operation tool.
In order to facilitate the operation of the steering control tool while suppressing the protruding length of the steering control tool from the upper surface of the control tower, the height of the upper surface at the position where the steering control tool of the control tower protrudes It is necessary to increase the height. Then, the height of the upper surface of the part located on the side of the part from which the steering operation tool of the control tower protrudes also becomes high, and it becomes difficult to put the knees up above the control tower, and the legs are placed behind the control tower. You must sit in a cramped position on the side.
