In addition, the clearance gap between the side column 30 and the horizontal part 31a is set as the clearance | interval which a driver | operator's hand can enter easily.

図４を用いて、機械式連動機構７５の配置について説明する。
機械式連動機構７５とは、操向ハンドル１２及び主変速レバー３５で操作された操作量を直進用ＨＳＴ機構７１と旋回用ＨＳＴ機構７２の各変速アームに適宜伝える機構である。操向ハンドル１２の操向操作を伝達するハンドル軸１３と、主変速レバー３５の主変速操作を伝達する主変速軸３３とは、機械式連動機構７５を介して、直進用ＨＳＴ機構７１及び旋回用ＨＳＴ機構７２に連動連結している。機械式連動機構７５は、ステアリングボックス５０に内蔵されている。ステアリングボックス５０は、ステップ１１の下方に配置されている。なお、本実施形態において、機械式連動機構７５の構成についての説明は省略する。 The arrangement of the mechanical interlocking mechanism 75 will be described with reference to FIG.
The mechanical interlocking mechanism 75 is a mechanism that appropriately transmits the amount of operation operated by the steering handle 12 and the main transmission lever 35 to each of the transmission arms of the straight traveling HST mechanism 71 and the turning HST mechanism 72. The steering shaft 13 that transmits the steering operation of the steering handle 12 and the main transmission shaft 33 that transmits the main transmission operation of the main transmission lever 35 are connected to the straight-travel HST mechanism 71 and the turn through a mechanical interlocking mechanism 75. It is linked to the HST mechanism 72 for use. The mechanical interlocking mechanism 75 is built in the steering box 50. The steering box 50 is disposed below the step 11. In the present embodiment, description of the configuration of the mechanical interlocking mechanism 75 is omitted.

機械式連動機構７５の機能について説明する。
機械式連動機構７５は、下記の各種動作を実行するために、主変速レバー３５や操向ハンドル１２からの操作力を適宜変換する機能を有する。
機械式連動機構７５によれば、主変速レバー３５を中立以外の位置に傾動操作した状態で、操向ハンドル１２を中立以外の位置に回動操作すると、その回動操作量が大きいほど小さな旋回半径でコンバイン１００が左又は右に旋回し、かつ旋回半径が小さいほどコンバイン１００の車速（前進及び後退時の旋回速度）が減速する、動作を実行できる。 The function of the mechanical interlocking mechanism 75 will be described.
The mechanical interlocking mechanism 75 has a function of appropriately converting operating forces from the main transmission lever 35 and the steering handle 12 in order to execute the following various operations.
According to the mechanical interlocking mechanism 75, when the steering handle 12 is rotated to a position other than neutral while the main transmission lever 35 is tilted to a position other than neutral, the smaller the turning operation amount, the smaller the turning. It is possible to execute an operation in which the combine 100 turns left or right at a radius and the vehicle speed of the combine 100 (the turning speed when moving forward and backward) decreases as the turning radius decreases.

また、機械式連動機構７５によれば、主変速レバー３５を前進及び後退のいずれの方向に傾動操作した場合であっても、操向ハンドル１２の回動操作方向とコンバイン１００の旋回方向とが一致する（操向ハンドル１２を左に回せばコンバイン１００が左旋回し、操向ハンドル１２を右に回せばコンバイン１００は右旋回する）、動作を実行できる。
さらに、機械式連動機構７５によれば、主変速レバー３５が中立位置にあると操向ハンドル１２を操作しても機能しない。 Further, according to the mechanical interlocking mechanism 75, the rotation operation direction of the steering handle 12 and the turning direction of the combine 100 are the same even when the main transmission lever 35 is tilted in either the forward or backward direction. The operations can be executed if they agree with each other (turning the steering handle 12 to the left turns the combine 100 to turn left and turning the steering handle 12 to the right turns the combine 100 to turn right).
Furthermore, according to the mechanical interlocking mechanism 75, if the main transmission lever 35 is in the neutral position, it does not function even if the steering handle 12 is operated.

図４及び図５を用いて、運転部１０の支持体２０について説明する。図４及び図５は、説明を分かり易くするため、支持体２０の正面カバー、上面カバー、ステップ１１上のペダル類、レバー類等の図示を省略している。   The support 20 of the operation unit 10 will be described with reference to FIGS. 4 and 5. In FIGS. 4 and 5, illustrations of the front cover, the top cover, the pedals on the step 11, the levers, and the like are omitted for easy understanding.

支持体２０は、ステップ１１上において操縦座席１４の前方に配置され、操向ハンドル１２と、ハンドル軸１３と、を支持するものである。また、支持体２０は、ステップ１１から鉛直方向に延出される支持部材２３・２４と、支持部材２３・２４の上方で支持部材２３・２４間に横架される軸支部材２１と、によって門構え形状に構成され、正面カバーと、上面カバーと、によって被装されている。   The support 20 is disposed in front of the control seat 14 on the step 11 and supports the steering handle 12 and the handle shaft 13. In addition, the support 20 is supported by a support member 23, 24 that extends in a vertical direction from the step 11, and a shaft support member 21 that is horizontally mounted between the support members 23, 24 above the support member 23, 24. It is configured in a shape and is covered by a front cover and a top cover.

支持部材２３・２４は、ステップ１１の前方であって、ステップ１１のハンドル軸１３の左右両側において、ステップ１１からそれぞれ鉛直方向において上向きに延出されている。また、支持部材２３・２４は、側面視において、上底よりも下底が長い台形の形状に形成されており、ステップ１１への設置面積を大きくし、ステップ１１に対する設置強度を高めている。   The support members 23 and 24 extend forward from the step 11 in the vertical direction on the left and right sides of the handle shaft 13 of the step 11 in front of the step 11. In addition, the support members 23 and 24 are formed in a trapezoidal shape having a lower bottom longer than an upper bottom in a side view, increasing the installation area to the step 11 and increasing the installation strength with respect to the step 11.

軸支部材２１は、正面視において、支持部材２３・２４の上部における支持部材２３・２４の内側において水平に掛け渡されるパイプ状の水平部２１ａと、水平部２１ａの左右方向中央部に配置され、コの字形状に形成され、内部にハンドル軸１３を挿通させることでハンドル軸１３を軸支する軸支部２１ｂと、を備えている。   The shaft support member 21 is arranged in a pipe-like horizontal portion 21a that extends horizontally inside the support members 23 and 24 above the support members 23 and 24, and in the center in the left-right direction of the horizontal portion 21a when viewed from the front. And a shaft support portion 21b that pivotally supports the handle shaft 13 by inserting the handle shaft 13 therein.

左補助支持部材としてのパイプ３１の鉛直部３１ｃは、正面視において水平部３１ａの前端から下方に湾曲し、軸支部材２１の水平部２１ａの左端部上面で支持固定している。なお、パイプ３１の鉛直部３１ｃは、支持部材２３を支持する構成であっても良い。   The vertical portion 31 c of the pipe 31 as the left auxiliary support member is curved downward from the front end of the horizontal portion 31 a in a front view, and is supported and fixed on the upper surface of the left end portion of the horizontal portion 21 a of the shaft support member 21. The vertical portion 31 c of the pipe 31 may be configured to support the support member 23.

右補助支持部材としてのパイプ４１は、側面視における支持部材２４の前後略中央において、シャーシ１から鉛直方向の上向きに延出し、パイプ３１の水平部３１ａと略同一の高さ位置において、正面視においてＵ字状に湾曲し、軸支部材２１の水平部２１ａの右端部上面に支持固定している。言い換えれば、パイプ４１は、正面視において、略逆「Ｊ」状に形成され、一端がシャーシ１に設けられ、他端が水平部２１ａに設けられている。なお、パイプ４１は、支持部材２４を支持する構成であっても良い。また、パイプ４１と支持部材２４との隙間は、操縦者の手が無理なく入ることができる間隔とされている。   The pipe 41 as the right auxiliary support member extends upward in the vertical direction from the chassis 1 at a substantially front and rear center of the support member 24 in a side view, and is viewed from the front at substantially the same height as the horizontal portion 31a of the pipe 31. And is supported and fixed to the upper surface of the right end portion of the horizontal portion 21a of the shaft support member 21. In other words, the pipe 41 is formed in a substantially inverted “J” shape when viewed from the front, with one end provided on the chassis 1 and the other end provided on the horizontal portion 21a. The pipe 41 may be configured to support the support member 24. Further, the gap between the pipe 41 and the support member 24 is set to allow the operator's hand to enter without difficulty.

本実施形態の効果について説明する。
従来、コンバインの機械式連動機構は、操縦席の前方に配置されたフロントコラム（支持体）に内蔵されていたため、フロントコラムを大きく設計する必要があった。また、操向ハンドルの振動が大きい場合には、操縦者が、長時間において操向ハンドルを握ることにストレスを感じるため、フロントコラムの剛性を高くする必要があった。そこで、従来の支持体は、アルミダイキャスト鋳造方法によって形成される大きなものが用いられていた。そのため、ステップ上において、操縦者の足元を広く設計することが困難であった。 The effect of this embodiment will be described.
Conventionally, the mechanical interlocking mechanism of the combine has been built in the front column (support) arranged in front of the cockpit, and thus the front column has to be designed to be large. Further, when the steering handle vibrates greatly, the operator feels stress in grasping the steering handle for a long time, and thus it is necessary to increase the rigidity of the front column. Therefore, a large support formed by an aluminum die casting method has been used as the conventional support. For this reason, it is difficult to design the pilot's feet widely on the step.

そこで、本実施形態のように、機械式連動機構７５を、ステップ１１の下方に配置し、支持体２０を、軸支部材２１と、支持部材２３・２４と、によって門構え形状に構成することで、ステップ１１上において、操縦者の足元を広く設計することができる。   Then, like this embodiment, the mechanical interlocking mechanism 75 is arrange | positioned under the step 11, and the support body 20 is comprised by the gate support shape by the axial support member 21 and the support members 23 and 24. In step 11, the operator's feet can be designed widely.

また、本実施形態のように、支持体２０の軸支部材２１を、サイドコラム３０に接続されているパイプ３１と、シャーシ１に接続されているパイプ４１と、によって上方から支持することで、シャーシ１においても強度が高いサイドコラム３０とシャーシ１とに軸支部材２１を支持することになり、軸支部材２１の支持強度を高めて、支持体２０の剛性を高めることができる。このようにして、操向ハンドル１２の振動を低減して、操縦者のストレスを解消できる。   Further, as in the present embodiment, the shaft support member 21 of the support 20 is supported from above by the pipe 31 connected to the side column 30 and the pipe 41 connected to the chassis 1. Also in the chassis 1, the shaft support member 21 is supported by the side column 30 and the chassis 1 having high strength, so that the support strength of the shaft support member 21 can be increased and the rigidity of the support body 20 can be increased. In this way, the vibration of the steering handle 12 can be reduced, and the operator's stress can be eliminated.

さらに、本実施形態のように、パイプ３１を、サイドコラム３０の外側輪郭を縁取るように配設することで、コンバイン１００が畦道を乗り越える際等において、車体が大きく傾く、或いは大きく振動する状況では、操縦者が、パイプ３１を把持することで、運転姿勢を保つことができる。   Further, as in the present embodiment, the pipe 31 is arranged so as to border the outer contour of the side column 30, so that the vehicle body is greatly inclined or vibrates greatly when the combine 100 gets over the tunnel. Then, the driver can maintain the driving posture by gripping the pipe 31.

また、本実施形態のように、パイプ４１を、支持部材２４の略中央において延出するように配設することで、操縦者が、操縦座席１４に搭乗する際に、パイプ４１を把持することで、コンバイン１００への乗降をアシストすることができる。   Further, as in the present embodiment, the pipe 41 is disposed so as to extend substantially at the center of the support member 24, so that the pilot grips the pipe 41 when getting on the control seat 14. Thus, getting on and off the combine 100 can be assisted.

このように、パイプ３１及びパイプ４１を、軸支部材２１を支持する機能のみならず、把持部としての機能を持たせることで、部品点数を削減できる。   Thus, the number of parts can be reduced by providing the pipe 31 and the pipe 41 not only with the function of supporting the shaft support member 21 but also with the function of the gripping part.

さらに、本実施形態のように、パイプ３１とパイプ４１とを、同じ断面形状のパイプを使用し、正面視において、パイプ３１の水平部３１ａとパイプ４１の湾曲部との位置を揃えることで、コンバイン１００の意匠性を向上している。また、共通の材料を使用することでコスト低減化を図っている。   Further, as in the present embodiment, the pipe 31 and the pipe 41 are the same cross-sectional shape pipes, and in the front view, by aligning the positions of the horizontal portion 31a of the pipe 31 and the curved portion of the pipe 41, The design of the combine 100 is improved. In addition, cost reduction is achieved by using a common material.
