Further, the roof panel portion 3u has reinforcing shape portions 60p and 60q that are formed to bulge downward.

  Next, functions and operations of the cabin 3 that is a main part of the speed sprayer 1 according to the present embodiment will be described with reference to FIGS.

  First, the cabin portion 3 including the door portion 16 has accessory arrangement portions 5p and 5q formed in a shape that bulges outward on the left and right cabin side surfaces Sp and Sq, and this accessory arrangement portion 5p. , 5q correspond to the positions of the front end surface parts 5ps, 5qs in the bulging direction corresponding to the positions of the outer surface parts 2bp, 2bq of the vehicle body 2, that is, the positions of the outer shell side parts 14p, 14q on the left and right sides of the chemical liquid tank 14. Yes.

  Accordingly, the cabin side surfaces Sp and Sq except for the accessory arrangement portions 5p and 5q are offset to the inner side of the cabin portion 3, that is, the driver's seat 4 side, and as shown in FIG. 1 (FIG. 2). The lateral width Wi (Wiu) of the cabin 3 is narrower than the original lateral width Wr (Wru), and the particularly heavy weight of the front window glass 58 is changed from the virtual line position 58s shown in FIG. The size of the cabin part 3 can be greatly reduced, and the size of the cabin part 3 can be significantly reduced. In the case of the example, the size is reduced by about 15%.

  As a result, the front window glass 58 can be reduced in weight, further reduced in other materials, and reduced in the weight of the cabin 3 by shortening the harnesses 11... And the pipings 12. Improvement can be achieved and the cost can be reduced. In addition, since the driver's seat 4 is arranged at the center position in the left-right direction of the cabin portion 3, the driver's comfort and drivability are not particularly impaired, and on the other hand, ease of getting on and off is improved and visibility is good. Become.

  In this case, the cabin portion 3 includes a cabin panel 3o formed of a plastic material R, and the door portion 16 includes a door panel 16o formed of the plastic material R. However, the cabin portion 3 has a shape that bulges outward. Since the accessory arrangement portions 5q and 5p are integrally formed, the required rigidity can be easily increased. As a result, the plastic material R can be sufficiently used, and advantages such as low cost, workability (manufacturability), and light weight can be enjoyed by using the plastic material R. In particular, since the accessory placement portions 5p and 5q are formed along the respective front-rear directions of the side panel 3q and the door panel 16o, the accessory placement portions 5p and 5q can also be used as a rib function. Particularly, the rigidity of Sp and Sq can be effectively increased, and the strength against impact from the lateral direction can be further increased. In the illustrated example, the cabin 3 has an entrance / exit 15 for entry / exit on at least one of the left and right cabin side surfaces Sp and Sq, and a door 16 that opens and closes the entrance / exit 15 is attached to the entrance / exit 15. The door portion 16 is provided with one accessory disposition portion 5p, but the one accessory disposition portion 5p is applied to the door portion 16 as it is. It can also be enjoyed by the door part 16 as it is.

  Moreover, since the hollow part located inside the accessory arrangement | positioning parts 5p and 5q becomes the accommodation channel parts 13p and 13q, it can utilize for the routing space of harnesses 11 ... and piping 12 ..., and it is a cabin side surface. It is possible to avoid the trouble that the inner surfaces of Sp and Sq are complicated, and to increase the space efficiency on the inner surface side of the cabin side surfaces Sp and Sq.

  Further, one or more accessories (17p, 17q, 18p, 18q, 19, 19s) provided on the cabin side surface Sp, Sq are arranged in the accessory arrangement portions 5p, 5q. At least one of the blinker lamps 17p and 17q, the rearview mirrors 18p and 18q, the door handle 19, and the keyhole 19s is included. Therefore, even if the lateral width Wi (Wiu) of the cabin portion 3 is reduced, general accessories necessary for the cabin portion 3 including the door portion 16, that is, the blinker lamps 17p and 17q, the rearview mirrors 18p and 18q, and the like. , The door handle 19 and the keyhole 19s can be arranged at the same positions as in the prior art. As a result, there are no problems that impair usability and convenience for the driver, and it is possible to avoid problems such as the blinker lamps 17p and 17q being difficult to see from the outside.

  On the other hand, the door portion 16 can open and close the entrance / exit portion 15 by rotationally displacing the hinge portion 33 attached to the front end side of the entrance / exit portion 15 for getting on and off the fulcrum. In this case, a part of the roof panel part 3u in the cabin part 3 and a part of the roof panel part 3u in the cabin part 3 are formed by extending the upper end side part and the rear end side part of the door panel 16o constituting the door part 16 in the cabin 3i side direction. Since the overhanging panel portions 51u and 51r that are part of the rear panel portion 3r are integrally formed, when the door portion 16 is closed, the door portion 16 and the cabin portion 3 may have a variation in dimensions due to materials or the like. However, adverse effects on the appearance can be eliminated. That is, conventionally, the gap generated by the upper end side and the rear end side of the door portion 16 moves to the upper surface side and the rear surface side of the cabin portion 3, so that when the door portion 16 is viewed from the side, The gap generated by the upper edge and the rear edge is hidden.

  Specifically, since the extended panel portions 51u and 51r are covered with the roof panel portion 3u and the rear panel portion 3r, a certain gap is generated between the front end side of the door portion 16 and the front end side of the doorway portion 15. At this time, there is a dimensional variation in the door portion 16 and the entrance / exit portion 15 (cabin portion 3), and even if the position of the rear end side of the door portion 16 deviates from the normal position, the appearance is improved. There is almost no adverse effect. That is, the chemical liquid tank 14 exists at a position behind the rear end side of the door portion 16, and the gap between the chemical liquid tank 14 and the door portion 16 is relatively wide. Therefore, the dimensional variation in the front-rear direction is relatively It becomes smaller and there is almost no adverse effect on the appearance due to dimensional variation. Similarly, since nothing exists above the upper end side of the door portion 16, there is almost no adverse effect on the appearance due to dimensional variations in the vertical direction. In this way, even when the door 16 and the cabin 3 are difficult to obtain dimensional uniformity due to materials or the like, adverse effects on the appearance due to dimensional variation can be eliminated, and the quality of the door 16 can be dramatically improved. Can be increased.

  In this case, since the extended panel portions 51u and 51r extending in a substantially right angle direction with respect to the planar door portion 16 are provided, the extended panel portions 51u and 51r can also function as a rib. Therefore, the rigidity and mechanical strength of the door portion 16 as a whole can be increased, and the safety can be further improved. In addition, since it can be seen as the door part 16 having a thick appearance, the solid feeling and the grade feeling of the door part 16 can be enhanced. In particular, in the present embodiment, since the accessory disposition portion 5p described above is provided in the door panel 16o, the rigidity is increased due to a synergistic effect obtained by combining the accessory disposition portion 5p and the overhanging panel portions 51u and 51r. Is increased.

  Further, the overhanging panel portion 51r formed integrally with the rear end side portion of the door panel 16o allows position adjustment from the outside with respect to at least the door striker portion 55s of the door lock mechanism 55 provided in the cabin portion 3. Since the cutout window portion 56 is provided, the position of the door striker portion 55s can be adjusted through the cutout window portion 56 with the door portion 16 closed as shown in FIG. That is, when performing the adjustment, while the door portion 16 is closed, a tool such as a nut turning is inserted from the outside through the notch window portion 56 to loosen the adjustment bolt nuts 57, 57 and the door striker portion 55s is optimized. After that, the adjustment bolt nuts 57, 57 may be tightened again. The setting of the door striker portion 55s at the optimum position includes not only optimization of the function of the door lock mechanism 55 but also fine adjustment such as enhancing the operational feeling and the degree of compression of the door packing.
