  Further, a floor 12 extending from the steering handle 6 to the cockpit 7 is provided at the bottom of the cabin, and fenders 13 are provided on both the left and right sides to cover the rear wheel 4 from the front to the top.

Next, the washer tank 26 provided on the rear surface of the cabin 9 as the main part of the present invention will be described.
The washer tank 26 is composed of a black plastic container, and as shown in FIGS. 2 to 5, a lid 26a is detachably provided on the top, and is opened to supply water when water is supplied. As shown in FIG. 2, the washer tank 26 has a left mounting bracket 30 </ b> L attached to the left side of the tank in the traveling direction of the vehicle, and the left mounting bracket 30 </ b> L is fixed to the rear panel 27 of the cabin 9. A pin shaft 29 that is slightly tilted rearward in the vertical direction along the panel 27 is passed through the support frame 28 and is rotatably attached by the pin 20.

  On the other hand, on the right end side of the tank 26, as shown in FIG. 3, a right side mounting bracket 30R which is bent in a U-shape when viewed from the side and has a vertical rod member 31 between the upper and lower sides. The rod member 31 is configured to be engaged and held with a holding tool (hereinafter referred to as a clip 33) that can be elastically displaced on the cabin side.

  Specifically, on the rear panel 27 side of the cabin 9, a guide stopper 34 having leaf spring-shaped guide portions 34a and 34b opened rearward in a side view is attached, and an open portion back portion of the guide stopper 34 is attached. The clip 33 is configured to be opened rearward. An opening 31a is opened at the lower side of the guide stopper 34, and the lower end 31a of the rod member 31 is engaged when the tank 26 is rotated and the one end thereof approaches the cabin. It is the composition to do.

  Further, at least one of the tubes 41 connected to the washer tank 26 and the spray nozzles 25F, 25R for spraying the cleaning water to the wipers 23F, 23R is a transparent tube so that the amount of liquid in the tank can be easily confirmed from the rear. I have a plan. Thereby, even if it is the black tank 26, the liquid quantity can be easily confirmed with the transparent tube 41. FIG. In arranging the tube 41, the clamp 42 held on the cabin side is arranged near the rotation fulcrum of the tank 26, and the tube 41 is prevented from being bent even if the tank 26 is rotated and displaced. Yes.

  In the tractor 1 configured as described above, when the washer tank 26 is attached to the vehicle body, the left mounting bracket 30L of the tank 26 is first overlapped with the support frame 28, and the pin shaft 29 is passed through and attached with the pin 20. The right mounting bracket 30R of the tank 26, specifically, the rod member 31 is clamped by the clip 33, and the lower end of the tank 26 is engaged with the opening of the guide stopper 34.

  When the washer tank 26 is filled with cleaning water or the like, the lower guide portion 34b of the guide stopper 34 is pushed downward lightly against the plate spring action, and the rod lower end 31a with respect to the opening 34h of the stopper 34 5 is released, the right side of the tank 26 is pulled out rearward, that is, the rod member 31 is removed from the clip 33, and is rotated to the left around the pin shaft 29 (the two-dot chain line in FIG. 5). Status).

  As a result, the lid 26a and the water supply port covered by the lid 26a are positioned on one side of the vehicle body, and the water supply operation is performed while the washer tank 26 is provided in the center of the vehicle body while avoiding the movable range of the lift arm 22. easy.

  The pin shaft 29 is an inclined shaft that is inclined in the front-rear direction along the rear panel 27 of the cabin 9. However, since the rod member 31 is sandwiched by the clip 33, the rod lower end 31a. Even if the engagement state is released, the tank 26 does not unexpectedly rotate and drop around the pin shaft 29 due to the weight of the tank 26, and the handling property is good.

When the washer tank 26 is locked (when the storage is fixed), the right mounting bracket 30R or the tank itself is inserted backward.
Thus, as the tank 26 moves rearward, the upper and lower portions of the right mounting bracket 30R are guided by the vertical guide portions 34a and 34b of the guide stopper 34, respectively, and enter the open portion of the bracket 30R. When the tank 26 is closed with respect to the rear surface of the rear panel 27, the rod member 31 is held between the clips 33, and at the same time, the lower end portion 31a of the rod member 31 is guided under the guide stopper 34. It engages with the opening 34h opened on the back side of the portion 34b (the state of the solid line in FIG. 5).

Thereby, at the time of tank lock, the tank 26 can be fixed by one-touch operation. Further, even when traveling on a rough road, the rattling between the rod member 31 and the clip 33 is regulated by the opening 45h of the guide stopper 34, so that it can be securely fixed without being inadvertently detached. Alternatively, the rod member 31 may be provided on the cabin 9 side, and the clip 33 and the guide stopper 34 that sandwich the rod member 31 may be provided on the tank 26 side.

Next, the configuration of the cabin 9 will be described in detail.
As shown in FIGS. 6 and 7, a lamp attachment for attaching the front and rear work lamps 48F, 48R,... To the roof front plate 46 and the roof rear plate 47 which are welded and fixed to the roof front frame 17 and the roof rear frame 18. The stay 49 is fastened and fixed by a mounting bolt 50 in the vertical direction. Further, as shown in FIG. 7, the mounting bolt 50 is arranged at a position behind the front work lamp 48F that cannot be seen from the irradiation direction view, thereby improving the appearance. Further, the work lamp 48 is configured to be able to rotate left and right and up and down using the horizontal shaft 51 and the vertical mounting bolt 50 as a rotation fulcrum, and the irradiation direction can be arbitrarily adjusted.

  Further, as shown in FIGS. 8 and 9, the rear glass 21 of the cabin 9 is configured to swing open and close in the front-rear direction via an open / close damper 53 with the hinge 52 in the horizontal direction as a fulcrum on the upper end side and closed. In some cases, the lock handle 54 is used for locking. The lock handle 54 is configured to attach and support a mark attachment stay 56 for attaching the low-speed vehicle mark 55. Conventionally, in a small tractor cabin, it is difficult to attach a low-speed vehicle mark having a large shape. In particular, the lower frame on the lower side of the rear glass cannot open and close the rear glass, and there are problems such as overlapping with the number plate or interfering with the lift arm 22 below the lower frame. Therefore, by using the lock handle 54 as in this example, the low-speed vehicle mark can be easily installed while ensuring sufficient visibility and comfort.

  Further, as shown in FIG. 10, in the cabin 9, the horizontal width (H1> H2) is sequentially increased toward the upper side of the black left and right glass screens 60, 60 provided on the windshield 19 with respect to the front frames 14, 14 parallel to the left and right. The shape is widened. Thereby, compared with the case where the glass screens 60 and 60 are provided in parallel with the left and right front frames 14 and 14, the upper part of the cabin appears visually thin, and the appearance of the cabin 9 can be improved.

  Similarly, in the cabin 9 of the present application in which the left and right front frames 14 and 14 are erected in parallel to the vehicle body center line, the rear frame 15 is viewed from the side as shown in FIG. The front wall portion 15a is perpendicular to the ground and the rear wall portion 15b is inclined so as to be in a forward inclined posture, and the upper end width D2 is narrower than the lower end width D1 (D1> D2). Further, the rear view of the rear frame 15 is also as shown in FIG. 13B. The inner wall side (cabin room side) 15c is perpendicular to the ground, and the outer wall side (cabin room outer side) 15d is the upper end side. It is set as the structure which inclines so that it may become so narrow (d1> d2).

  Thereby, the upper part of the cabin 9 looks visually thin, and the aesthetics of the design can be improved. In addition, the code | symbol 61 in FIG. 11 shows the door switch for room lamps, and can be installed in the wide part of the lower end side of the said rear frame 15. FIG.

  Further, as shown in FIG. 14A, the interior cover 63 attached to the rear frame 15 is also configured such that the upper portion of the cover shape is small (K1> K2) in the rear view. Further, in a side view, as shown in FIG. 14B, the upper part is configured to be narrower than the lower part (S1> S2).

  Thereby, like the above, the aesthetics can be improved by visually showing the upper part of the cabin thinly.
