As shown in FIGS. 8 and 10, the boarding / alighting handle 50c is provided as a side view over a place where the driver's seat 50 is mounted and a place standing on the back side thereof in the floor plate upper portion 51a in the driving cabin 5. It is composed of a U-shaped member in a side view attached to the inverted L-shaped mounting member 51d.

[Operation box]
As shown in FIGS. 8 and 12, the operation box 6 for maneuvering operation provided at the right lateral end of the operation cabin 5 has a steering lever 61, a combination switch 62, and a key switch on the upper surface side of the box body 60. 63 is equipped. Then, the box body 60 of the operation box 6 is placed on the right front side of the driver's seat 50 with respect to the support 52a on the right front side, which is the side on which the door 55 for getting on and off of the driving cabin 5 is provided, via the mounting member 6a. It is fixedly supported in a cantilever shape.
In the state where the box body 60 is supported by the support column 52a, the operation box 6 is located on the front side of the box body 60 in a plan view, and on the left and right sides of the operation cabin 5 toward the end side in the left-right direction of the operation cabin 5. It is equipped with a front surface 60a that is inclined so that the center side in the direction is closer to the rear, and the rear side is also closer to the front in the left-right direction of the driving cabin 5 in a plan view and is closer to the front in the left-right direction of the driving cabin 5. It is provided with a rear surface 60b that is inclined so as to be closer to the rear toward the center side.
As a result, when the operator seated in the driver's seat 50 looks at the box body 60, the horizontal width of the box body 60 looks short.

That is, for example, as shown by a virtual line in FIG. 8, if the box body 60 is composed of a simple rectangular object with the front side facing the front side of the machine and the rear side facing the rear side of the machine, the box seen from the driver's seat 50 side. The horizontal width of the main body 60 is the left and right corners of the driving cabin 5 on the front side of the box body 60 and the left and right corners of the driving cabin 5 on the rear side of the box body 60. It is wide enough to correspond to the diagonal length connecting the parts.
The box body 60 in the present invention is not such a rectangular box body 60, but as described above, the end side in the left-right direction of the driving cabin 5 is closer to the front and the center side in the left-right direction of the driving cabin 5. The front surface 60a is tilted toward the rear, and the end side of the driving cabin 5 in the left-right direction is tilted toward the front and the center side of the driving cabin 5 is tilted toward the rear in the left-right direction. It has a rear surface 60b.
Therefore, the projection lines L1 and L2 from the central position O to the left-right end of the box body 60 are the projection lines L1 and L2 from the central position O of the seat surface 50a of the driver's seat 50, which is the position where the driver is present in a plan view. The width is narrower than the projection lines L1'and L2'to the left-right end of the rectangular box body 60 (see the virtual line in FIG. 8) described above. This makes it possible to secure a wide field of view for the operator.

The steering lever 61 and the combination switch 62 provided on the upper surface side of the box body 60 are such that the steering lever 61 is located closer to the rear side near the driver's seat 50, and the combination switch 62 is the driver's seat than the steering lever 61. It is provided on the front side far from 50.
As shown in FIGS. 5, 9 and 11, the mounting position of the operation box 6 is a position higher than the seat surface 50a of the driver's seat 50, and the inner gripping member mounted on the indoor side of the boarding / alighting door 55. The upper surface of the box body 60 is provided so as to be located at a position slightly higher than 55f.
Further, as shown in FIGS. 8 and 9, the steering lever 61 for steering operation provided in the operation box 6 is positioned from the front of the driver's seat 50 in the position of the operation box 6 in a plan view. Is located slightly off the right outside.
That is, since the steering lever 61 is arranged in the driving cabin 5 at a position deviated laterally from the position immediately before the driver's seat 50 in the left-right direction, the steering lever 61 corresponds to the operating tool for maneuvering operation. The steering lever 61, the box body 60, which corresponds to the support structure for attaching the steering lever 61, and the like are excluded from the position immediately before the driver's seat 50, and almost nothing obstructs the front view in front of the driver's seat. There is a space S0 between the driver's seat 50 and the lower part of the windshield 54 located immediately before the driver's seat 50 so that the lower part of the front side of the driving cabin 5 can be seen. As a result, it was possible to improve the visibility of the front and lower parts of the driving cabin 5 while seated in the driver's seat 50.

As shown in FIGS. 4 and 11, the operation box 6 is arranged so as to be located on the front side of the machine body with respect to the lower end of the support column 52a on the right front side of the operation cabin 5 in a side view. Therefore, when getting on and off the driving cabin 5, the passenger gets on and off the area above the floor surface 5A in the driving cabin 5 located on the rear side of the machine body from the lower end of the support column 52a on the right front side of the driving cabin 5. It is less likely that the operator will come into contact with the operation box 6 provided on the front side outside the area.

The operation box 6 is located on the front side of the machine body from the lower end of the support column 52a on the right front side of the operation cabin 5 in a side view, but as shown in FIGS. 8 and 11, the operation box 6 is located on the windshield 54. It is provided at a distance from the windshield 54. This ensures that when the steering lever 61 provided on the upper side of the operation box 6 is oscillated from front to back and left and right, a sufficient oscillating range to the front side is secured so that the oscillating operation can be performed without any trouble. Is for.

The steering lever 61 for steering operation is supported by the box body 60 so that it can be swung in the front, rear, left, and right cross directions. The operating position of the steering lever 61 is detected by a position detector (not shown) built in the box body 60, and the operating position of the steering lever 61 is steered by a mechanical linkage mechanism such as a link mechanism.
