Tilt forward around 7 and 17 ', fold, interfere with the car body, and stop.

The bracket 9 of the rotary light 8 is attached to the roof 1 and is held at a position higher than the roof 1 in both a normal posture and a folded posture (FIGS. 18 and 20). reference).

[0006]

The conventional fixed canopy shown in FIG. 17 and the conventional four canopies shown in FIGS.
The point link type canopy has the following problems. (1) The fixed canopy shown in FIG. 17 cannot be folded. When the motor grader 37 is transported by a vehicle such as a truck, it is necessary to remove the canopy from the motor grader 37 in order to reduce the vehicle height. there were.

In the four-point link canopy shown in FIGS. 18 to 20, when the roof 1 shifts from the normal posture to the folding posture shown in FIG. 20, all of the weight of the roof 1 is transferred to the front upper struts 29 and the rear upper struts 31. In addition, these columns 29 and 31 may be sharply inclined forward, which is dangerous. Also, when shifting from the folded position to the normal position, it is necessary to manually lift the weight of the roof 1 by hand, which requires a great deal of labor. (2) In the motor grader 37, not only the field of view during running but also the field of view to the blade 36 during operation is important. However, when a glass is provided on the front of the canopy, the column is not provided in the fixed canopy shown in FIG. It is fixed, and glass can be mounted on the entire front surface, but it is difficult to mount glass on the full front surface in the four-point link type canopy shown in FIGS. In addition, even if the glass was fully loaded on the front, it had to be removed when folded. (3) In the four-point link type canopy shown in FIGS. 18 to 20, since the pin 17 at the bending point of the column is on (or near) the center line of the column, the glass is divided vertically and attached to the front surface. However, when folded as shown in FIG. 21, the front upper window frame 10 'and the front lower window frame 11' approach. Therefore, at the time of the normal posture shown in FIG. 22, the front upper window frame 10 'and the front lower window frame 11' need to be considerably separated from each other. After flowing into the canopy, it can no longer serve as a windshield. In addition, the area of the window glass is reduced, and the visibility is deteriorated. In FIGS. 21 and 22, 14 'is a front upper window glass, and 15' is a front lower window glass. (4) In the four-point link type canopy shown in FIGS. 18 to 20, the front upper column 29 and the rear upper column 31 are left and right independent one by one, and each is pivotally supported by the roof 1 via a pin. 19, the canopy is apt to rattle in the left-right direction as shown in FIG. (5) In the four-point link type canopy shown in FIGS. 18 to 20, it cannot be locked by a bolt or the like in the folded position, so that it may vibrate during transportation and may be dangerous and may be damaged. (6) Normally, the rotating light 8 is mounted on the roof 1 so as to be visible from the surroundings. However, in the four-point link type canopy shown in FIGS. 18 to 20, even when the roof 1 is lowered in the folded position, the rotating light 8 is located on the roof 1, so the rotating light 8 needs to be removed from the roof 1. Was.
