Next, an operation of moving the sun visor 20 of the combine 1 from the storage position to the use position by the operator will be described.
In a state where the backrest 12 is rotated downward to be in the use position, the operator grips the outer end of the body 21 of the frame 21 of the sun visor 20 and is placed in the storage position (the frame 21 of the sun visor 20). Is moved linearly (in parallel with the upper surface of the grain tank 9) so as to be pulled out to the outside of the machine body. At this time, the lock body 41 of the lock part 40 is moved to the outside of the machine body from the base member 33 of the support part 30, and the lower part of the lock body 41 of the lock part 40 and the surface of the abutment body 42 abut on the outside of the machine body. The frame 21 of the sun visor 20 is moved until the hood 22 of the sun visor 20 protrudes outside the grain tank 9 (see FIG. 6 or FIG. 7).
Next, the frame 21 of the sun visor 20 is rotated slightly upward together with the support member 32 of the support portion 30 to be inclined (see FIG. 8).
Next, the sun visor 20 is tilted so that the contact body 42 of the lock portion 40 contacts the support member 32 of the support portion 30 and the contact body 42 of the lock portion 40 is positioned below the lock body 41. The frame 21 is moved further outward (see FIG. 9).
Next, the frame 21 of the sun visor 20 is rotated slightly downward together with the support member 32 of the support portion 30, and the contact body 42 of the lock portion 40 is disposed so as to be brought into contact with the lock body 41 and hooked. The sun visor 20 is fixed at the use position (see FIG. 10).
In this manner, the operator moves the sun visor 20 from the storage position to the use position.

Next, an operation of moving the sun visor 20 of the combine 1 from the use position to the storage position by the operator will be described.
An operator grasps the outer end of the body 21 of the frame 21 of the sun visor 20, rotates the sun visor 20 (frame 21 of the sun visor 20) disposed at the use position slightly upward together with the support member 32 of the support unit 30, The state in which the contact body 42 of the lock part 40 is brought into contact with the lock body 41 and is caught (the state where the sun visor 20 is fixed at the use position) is eliminated.
Next, the frame 21 of the sun visor 20 is moved so as to be pushed toward the center of the machine body so that the contact body 42 of the lock unit 40 is located closer to the machine body than the lock body 41.
Next, the sun visor 20 together with the support member 32 of the support portion 30 so as to be (in parallel with the upper surface of the grain tank 9) in a state where the contact body 42 of the lock portion 40 is located closer to the center of the body than the lock body 41. 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.

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.

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.

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.

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.

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.

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.

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.

When the backrest 12 of the combine 1 is not used (when the backrest 12 is set to the storage position), the sun visor 20 is disposed at the storage position so that the sun visor 20 cannot move from the storage position to the use position. 20 positions can be held (see FIG. 2).
The backrest 12 is stored in the vicinity of the outside of the sun visor 20 (the frame 21 of the sun visor 20) when the backrest 12 is in the storage position with the sun visor 20 placed in the storage position. It is comprised so that it may be located on the movement path | route which moves to a use position from a position. When the backrest 12 is in the storage position with the sun visor 20 disposed at the storage position, the backrest 13 is positioned outside and above the grain tank 9 and used from the storage position. The backrest 13 is configured to contact the sun visor 20 (the frame 21 of the sun visor 20) to which the sun visor 20 (the frame 21 of the sun visor 20) is to move.

As described above, the backrest 12 is configured to be able to hold the position of the sun visor 20 arranged at the storage position so that the sun visor 20 cannot move from the storage position to the use position when the backrest 12 is set to the storage position. In the combine 1, the backrest 12 holds the position of the sun visor 20 disposed at the storage position so that the sun visor 20 cannot move from the storage position to the use position. The sun visor 20 can be prevented from moving (jumping out).

As described above, when the backrest 12 is in the storage position with the sunvisor 20 placed in the storage position, the backrest 13 of the backrest 12 is used from the storage position in the vicinity of the outside of the sunvisor 20. In the combine 1 configured to be located on the movement path that moves to the position, when the backrest 12 is set to the storage position with the sun visor 20 disposed at the storage position, the combine 1 tries to move from the storage position to the use position. The sun visor 20 is in contact with the backrest 13 of the backrest 12, and the sun visor 20 cannot move from the storage position to the use position.
Therefore, in the combine 1, what can prevent the sun visor 20 from moving unintentionally from the storage position to the use position can be realized with a simple configuration.

The attachment member 31 of the support portion 30 of the combine 1 includes a plurality (three) of fixing holes 35, and the lock body 41 of the lock portion 40 includes the fixing holes 43.
