The frame 21 is slightly rotated upward.
Next, the frame 21 of the sun visor 20 is moved to the fuselage center side so as to slide on the upper surface of the upper portion of the base member 33 of the support portion 30, and the frame 21 and the hood 22 of the sun visor 20 are moved outward from the grain tank 9. Arrange so that it does not protrude.
In this manner, the operator moves the sun visor 20 from the use position to the storage position.
 以上のように、支持部30の支持部材32は、サンバイザ20の出退動作(収納位置から使用位置にサンバイザ20を移動させる動作、または、使用位置から収納位置にサンバイザ20を移動させる動作)が直線的となるようにサンバイザ20を支持する、コンバイン1では、サンバイザ20の出退動作(サンバイザ20の出退動作時における、ロック部40によってサンバイザ20を使用位置に固定する動作以外の動作、または、ロック部40によって使用位置に固定された状態を解除する動作以外の動作)が直線的となるようにサンバイザ20が支持されることから、サンバイザ20の出退動作を行うときに、サンバイザ20を大きく上方に回動させることを要さない。
 このため、前記コンバイン1では、サンバイザ20の出退動作を行うときに、例えば、作業者が、腕を上方に高く上げること、または、背伸びをすること等を要さずに、サンバイザ20の出退動作を行うことができる。
 したがって、コンバイン1によれば、サンバイザ20を大きく上方に回動させるものに比べて、作業者によるサンバイザ20の出退動作を容易に行うことができる。
 また、コンバイン1によれば、出退動作が直線的となるようにサンバイザ20が支持されることから、狭い倉庫にコンバイン1が格納された状態でもサンバイザ20の出退動作を行うことができる。
As described above, the support member 32 of the support unit 30 is configured to allow the sun visor 20 to move in and out (an operation for moving the sun visor 20 from the storage position to the use position or an operation for moving the sun visor 20 from the use position to the storage position). In the combine 1 that supports the sun visor 20 so as to be straight, the operation of the sun visor 20 (operation other than the operation of fixing the sun visor 20 to the use position by the lock unit 40 during the operation of the sun visor 20, or The sun visor 20 is supported so that the operation other than the operation of releasing the state fixed to the use position by the lock unit 40 is linear. There is no need to rotate it upward.
For this reason, in the combine 1, when the sun visor 20 is moved in and out, for example, the operator does not need to raise his arm upward or stretch his back, and so on. A retreat can be performed.
Therefore, according to the combine 1, compared with what rotates the sun visor 20 largely upwards, the operation | movement of the sun visor 20 by an operator can be performed easily.
Moreover, according to the combine 1, since the sun visor 20 is supported so that the leaving / leaving operation is linear, the leaving / leaving operation of the sun visor 20 can be performed even when the combine 1 is stored in a narrow warehouse.
 以上のように、ロック部40がサンバイザ20を使用位置に固定するコンバイン1では、サンバイザ20の出退動作が直線的となるように構成されるものであっても、例えば、コンバイン1の走行中に、意図せずに、サンバイザ20が使用位置から収納位置に移動することを防止することができる。 As described above, in the combine 1 in which the lock unit 40 fixes the sun visor 20 in the use position, for example, even when the combiner 1 is configured so that the operation of the sun visor 20 is linear, In addition, it is possible to prevent the sun visor 20 from moving from the use position to the storage position unintentionally.
 以上のように、ロック部40が、サンバイザ20の使用位置においてサンバイザ20が上方に傾斜した姿勢で固定されるように構成される、コンバイン1では、サンバイザ20の使用位置においてサンバイザ20が上方に傾斜した姿勢で固定されることから、例えば、サンバイザ20の下方にいる作業者の頭部がサンバイザ20(サンバイザ20の幌22)に接触すること、または、サンバイザ20に頭部が当接してしまう作業者が屈んだ状態で穀粒の袋詰め作業を行うこと等を回避することができる。 As described above, in the combine 1 in which the lock unit 40 is configured to be fixed in a posture in which the sun visor 20 is inclined upward at the use position of the sun visor 20, the sun visor 20 is inclined upward at the use position of the sun visor 20. For example, the operator's head below the sun visor 20 comes into contact with the sun visor 20 (the hood 22 of the sun visor 20) or the head contacts the sun visor 20 because the head is in contact with the sun visor 20. It is possible to avoid the grain bagging operation in a state where the person is bent.
 以上のように、ロック部40は、支持部30に配置されるロック部40のロック体41と、サンバイザ20のフレーム21から突出するロック部40の当接体42と、を備え、サンバイザ20を使用位置に移動させた状態において、ロック部40の当接体42がロック体41に当接して引掛ることによってサンバイザ20を使用位置に固定する、コンバイン1では、ロック部40の当接体42がロック体41に当接して引掛ることによってサンバイザ20を使用位置に固定することから、サンバイザ20を使用位置に固定することができるものを簡易な構成で実現することができる。 As described above, the lock unit 40 includes the lock body 41 of the lock unit 40 disposed on the support unit 30 and the contact body 42 of the lock unit 40 protruding from the frame 21 of the sun visor 20. In the state of being moved to the use position, the abutment body 42 of the lock unit 40 fixes the sun visor 20 at the use position by being brought into contact with the lock body 41 and hooked. Since the sun visor 20 is fixed to the use position by being brought into contact with and hooked to the lock body 41, it is possible to realize what can fix the sun visor 20 to the use position with a simple configuration.
 以上のように、ロック部40の当接体42が、支持部30の支持部材32よりも機体中央側において、サンバイザ20のフレーム21から上方に突出するように配置される、コンバイン1では、サンバイザ20のフレーム21が、支持部30の支持部材32(支持部材32の上部と取付部材31の内側の面との間に形成された略筒状の空間)に貫挿されて支持された状態から機体外側に移動していくと、ロック部40の当接体42が支持部30の支持部材32に当接する。
 このため、コンバイン1では、サンバイザ20を使用状態とするときに、支持部材32に貫挿されたサンバイザ20のフレーム21が当該支持部30の支持部材32から脱落することを防止することができる。
As described above, in the combine 1 in which the abutment body 42 of the lock portion 40 is disposed so as to protrude upward from the frame 21 of the sun visor 20 on the center side of the body relative to the support member 32 of the support portion 30. From the state in which the 20 frames 21 are inserted into and supported by the support member 32 of the support portion 30 (substantially cylindrical space formed between the upper portion of the support member 32 and the inner surface of the mounting member 31). As it moves to the outside of the machine body, the abutment body 42 of the lock portion 40 abuts on the support member 32 of the support portion 30.
For this reason, the combine 1 can prevent the frame 21 of the sun visor 20 inserted through the support member 32 from dropping from the support member 32 of the support portion 30 when the sun visor 20 is put into use.
 以上のように、サンバイザ20が収納位置に配置されるときに、サンバイザ20のフレーム21が穀粒タンク9の上面に当接しないように載置される支持部30の台部材33を備えるコンバイン1では、サンバイザ20が収納位置に配置されるときに、サンバイザ20のフレーム21が穀粒タンク9の上面に当接することによって、穀粒タンク9が破損する虞を回避することができる。 As described above, the combine 1 including the base member 33 of the support portion 30 placed so that the frame 21 of the sun visor 20 does not come into contact with the upper surface of the grain tank 9 when the sun visor 20 is disposed at the storage position. Then, when the sun visor 20 is disposed at the storage position, the frame 21 of the sun visor 20 comes into contact with the upper surface of the grain tank 9, thereby avoiding the possibility of the grain tank 9 being damaged.
 以上のように、支持部30の台部材33の外側部が、台部材33の上部の機体外側縁部から下方に突出して、台部材33の上部の下方の機体外側の空間を閉じるように構成される、コンバイン1では、サンバイザ20を使用位置から収納位置に移動させるときに、ロック部40の当接体42がロック体41に当接させて引っ掛った状態を解消させた後、サンバイザ20のフレーム21が穀粒タンク9の上面と並行になっていない状態で機体中央側にサンバイザ20のフレーム21を移動させると、サンバイザ20のフレーム21の機体中央側端部が台部材33の外側部に当接して、サンバイザ20のフレーム21の機体中央側への移動ができなくなる。
 したがって、コンバイン1では、サンバイザ20を使用位置から収納位置に移動させるときに、サンバイザ20のフレーム21が、穀粒タンク9の上面と並行になっていない状態で機体中央側に移動した場合に、台部材33の上部の下方に入り込むことを防止することができる。
As described above, the outer portion of the base member 33 of the support portion 30 protrudes downward from the upper outer edge of the base member 33 and closes the space outside the upper lower portion of the base member 33. In the combine 1, after the sun visor 20 is moved from the use position to the storage position, after the contact body 42 of the lock unit 40 is brought into contact with the lock body 41 and the hook is released, the sun visor 20 is removed. When the frame 21 of the sun visor 20 is moved to the center side of the machine body in a state where the frame 21 is not parallel to the upper surface of the grain tank 9, the machine body side edge of the frame 21 of the sun visor 20 is the outer part of the base member 33. The frame 21 of the sun visor 20 cannot be moved toward the center of the machine body.
Therefore, in the combine 1, when the sun visor 20 is moved from the use position to the storage position, when the frame 21 of the sun visor 20 moves to the center side of the body without being parallel to the upper surface of the grain tank 9, It is possible to prevent entry into the lower part of the upper portion of the base member 33.
 コンバイン1の背凭れ12は、背凭れ12を使用しないとき(背凭れ12を収納位置とするとき)には、サンバイザ20が収納位置から使用位置に移動できないように、収納位置に配置されるサンバイザ20の位置を保持可能に構成される(図2参照)。

 また例えば、支持部30の取付部材31の上方の固定孔35を選択してロック部40のロック体41を取付部材31に取付けた場合には、サンバイザ20が穀粒タンク9の上面に対してサンバイザ20が略45度傾斜した姿勢となる(図22参照)。
In the combine 1, for example, when the fixing hole 35 below the attachment member 31 of the support portion 30 is selected and the lock body 41 of the lock portion 40 is attached to the attachment member 31, the sun visor 20 is used at the use position of the sun visor 20. (The hood 22 of the sun visor 20) is inclined by approximately 15 degrees with respect to the upper surface of the grain tank 9 (see FIG. 20).
Further, for example, when the fixing hole 35 above the attachment member 31 of the support part 30 is selected and the lock body 41 of the lock part 40 is attached to the attachment member 31, the sun visor 20 is against the upper surface of the grain tank 9. The sun visor 20 is inclined approximately 45 degrees (see FIG. 22).
 以上のように、サンバイザ20の使用位置における傾斜角度を変更可能に構成される、コンバイン1では、例えば、サンバイザ20の下方において穀粒を袋に詰める作業を行う作業者の身長や日照角度等に合わせて、サンバイザ20がより確実に日よけとして機能するように、サンバイザ20の使用位置における傾斜角度を適宜選択して変更することができる。 As described above, in the combine 1 configured so that the inclination angle at the use position of the sun visor 20 can be changed, for example, the height or sunshine angle of the worker who performs the work of packing the grains in the bag below the sun visor 20. In addition, the inclination angle at the use position of the sun visor 20 can be appropriately selected and changed so that the sun visor 20 functions as a sunshade more reliably.
 また、図23から図25に示すように、コンバイン1は、一対のフレーム台14を備える構成とすることもできる。 Further, as shown in FIG. 23 to FIG. 25, the combine 1 may be configured to include a pair of frame bases 14.
 このように、フレーム台14を備えるコンバイン1では、サンバイザ20が収納位置に配置されるときに、フレーム台14によってサンバイザ20のフレーム21の機体中央側端部を下方から支えるようにして、サンバイザ20のフレーム21を撓みにくくすることができる。
 したがって、コンバイン1によれば、サンバイザ20が収納位置に配置されるときに、サンバイザ20のフレーム21が撓んで穀粒タンク9の上面に当接して穀粒タンク9が破損する虞を回避することができ、また、サンバイザ20のフレーム21が長時間継続して撓んで変形するような状態を回避することができる。
Thus, in the combine 1 provided with the frame base 14, when the sun visor 20 is arrange | positioned in a stowed position, the frame base 14 supports the body center side edge part of the flame | frame 21 of the sun visor 20 from below, and the sun visor 20 is supported. The frame 21 can be made difficult to bend.
Therefore, according to the combine 1, when the sun visor 20 is arrange | positioned in a stowed position, the flame | frame 21 of the sun visor 20 bends and it abuts on the upper surface of the grain tank 9, and avoids a possibility that the grain tank 9 may be damaged. In addition, it is possible to avoid a state in which the frame 21 of the sun visor 20 is continuously bent and deformed for a long time.
