25 are provided with bolts 26 and 27 to be screwed into .

According to a second aspect of the present invention, the height of the reinforcing mounting member 12 is substantially the same as the height of the rear wheel fender 17.
Characterized in that the ropes support 21 is attached via the.

[0006]

According to the present invention, the upright surface portion 18 of the rear wheel fender 17 is fixed to the reinforcing mounting member 12 to make the fender 17 rigid, and the lops support 21 is attached to reduce the number of parts, thereby reducing costs. do. Also, the reinforcing mounting member 1
By joining the 2 and the ropes support 21 with the joint separating means 22, it is not necessary to significantly improve the structure for the ropes specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 4, a tractor body 1 shown as a two-axis four-wheel tractor also serves as a transmission case, and a hydraulic device 3 having a pair of left and right lift arms 2 is mounted on the rear upper surface. The hydraulic device 3 is covered from above by a floor sheet 4, and steps 5 provided on the left and right front portions of the floor sheet 4 are fixed to side portions of the tractor vehicle body 1 by fastening means 6.

A driver's seat 8 is provided on the floor seat 4 above the hydraulic device 6 via support means 7. A rear axle case 10 is connected to a rear left and right side surface of the tractor body 1 via a final deceleration case 9, and supports a rear wheel 11 driven by a drive shaft inserted into the case. The left and right rear axle cases 10 are provided with upright reinforcing attachment members 12, and the members 12 overlap a lower base plate 13 on the upper surface of the case 10, and a plate member (not shown) and a base plate which are overlapped on the lower surface of the case 10. 13, the case 10 is clamped and fixed upright by fastening means 14.

The reinforcing mounting member 12 is a hollow steel material having a rectangular or circular cross section. A base plate 13 is welded to the lower end, and a streak 15 is welded inside the base plate 13 to strengthen the lower portion. Have been. The reinforcing mounting member 12 is inclined upward in a rearward direction, and an outer surface 18 of a rear wheel fender 17 is fixed to the outside of the reinforcing mounting member 12 via fixing means 16. , And a lower front portion is attached to the step 5 by fastening means 20.

The reinforcing mounting member 12 has an upright height substantially equal to that of the rear wheel fender 17, and has a gate-shaped lopes 21 when viewed from the front and rear.
Are attached by the joint separating means 22. The rope support 21 is connected to the reinforcing mounting member 12 by the joining / separating means 22 so that the rope support 21 forms a so-called two-post type rope, and stands upright at the rear of the driver's seat 8 in a rear-up slope. As shown in FIG. 4 (A), the joining / separating means 22 is adapted to be fitted into the upper fitting portion 12A of the reinforcing attachment member 12 and the lower fitting portion 21A of the rope support 21 so as to be freely inserted and removed. 23, and the connecting body 23 is
The bolts 26 and 27 are screwed from the outside to the upper and lower nuts 24 and 25 which are fitted over and welded to the connecting body 23 and fastened, whereby the two 12 and 21 are joined.

That is, after connecting the connecting body 23 to the reinforcing mounting member 12 with the nut 25 and the bolt 27, the ropes column 21 is fitted to the connecting body 23 and the nut 24 and the bolt 26 are fastened. When the ropes are unnecessary, the plug 23 may be detachably attached to the upper part of the reinforcing attachment member 12 by removing the connecting body 23. Your name, a pair of left and right rear wheel fenders 17
Of the front and rear supports 2 installed between them
Connected to each other by 8, 29
Numeral 8 supports the floor sheet 4 with a stopper 30, and the rear support 29 has an elastic holder 32 and the like that make the top link 31 detachable.

The front and rear supports 28 and 29 are shown in FIG.
An end plate 33 is welded to both ends of the angle material as shown in FIG.
It is concluded with. A plurality of fixing means 16 are provided at intervals in the height direction, and a web of a channel-shaped connecting member 16A welded to the reinforcing mounting member 12 is superimposed on the upright portion 18 as shown in FIG. It is fastened with bolts 16B.

[0013]

As described in detail above, according to the present invention, the rear wheel fender can be rigidly mounted and the ropes support can be similarly rigidly mounted. In this case, the cost can be reduced by using the same parts. Further, regardless of the presence or absence of the ropes, the rear wheel fender support portion does not require a significant design change, and the cost can be reduced in this regard.
