DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A tractor body 6 has a front axle bracket 7, a clutch housing 8, a transmission case 9 and the like connected from a front portion thereof. And a rear axle housing 1 on both left and right sides of the transmission case 9.
2 to support the rear wheel 13 so that it can be driven,
Each of them is configured to be driven in conjunction with the engine 14. [0007] At the top of the transmission case 9 is a cockpit 1
5 and a steering handle 17 at the front of the step floor 16. A floor 19 is provided from the fender 18 on the upper side of the rear wheel 13 to the upper side of the transmission case 9 in the center, and is supported by the lower frame 20 on the transmission case 9 and the rear axle housing 12. [0010] The frame structure of the cabin 21 includes a front support column 23 located on the lateral outside of the dashboard 22, a cockpit 15.
A rear connecting post 25 positioned on the laterally outer side of the rear portion, a front connecting frame 25 connecting lower end portions of these left and right front supporting columns 23,
The four corners of the roof frame 1 having a rectangular shape in plan view are connected between the rear connection frame 26 connecting the lower ends of the left and right rear supports 24 to each other, and between the upper ends of the front supports 23 and the rear supports 24. The front connecting frame 25 is superposed on the dashboard 22 and the rear connecting frame 26 is mounted on the lower frame 20 at the rear of the transmission case 9. The parts are connected to each other by a front part and a rear part of the fender 18 and mounted on the vehicle body 6. A windshield 27 is provided between the front supports 23 of such a cabin 21 frame, a rear glass 28 is provided between the rear supports 24 so as to be openable and closable, and a rear support is provided between the left and right front and rear supports 23, 24. A door 30 is provided to the door 24 so as to be freely opened and closed with a hinge 29. The roof frame 1 is made of sheet metal and formed hollow by joining and joining an outer member and an inner member, and the outer member is exposed to the outside of the cabin. Also, the inner member is exposed in the cabin. The front side portion 3 forms a mounting edge 32 for mounting the upper edge of the windshield 27 via a seal 31 at the lower front side, and the rear side edge forms a step portion 33 to form the roof panel 5. The front edge portion can be superimposed on the lower edge portion 34 of the step portion 33, and can be joined by welding, bolts, nuts, or the like. Further, the left and right side portions 4 are continuously formed in the same manner, and the upper surface is formed to be narrower than the front side portion 3 so as to reduce the amount of rain diverted to the outside. The rear side 2 does not form the step 33,
An upper end surface 35 is formed on a surface at the same height as the lower edge portion 34, and the rear edge portion of the roof panel 5 is overlapped and joined on the upper end surface 35. 36 is a lining board. In addition, the roof frame 1 is assembled and constructed by overlapping A in the form of insertion from the front and rear sides 4 on the left and right sides. In such a configuration, it is possible to assemble with a fastener such as a bolt. In addition, it is possible to share the case where the lengths in the front-back direction are different due to the different models. The door 30 is connected to the rear support 24 by a hinge 29.
A glass frame 38 made of a thick pipe material and a glass frame 43 made of a pipe material thinner than the glass frame 38 are attached to the glass frame 38 so as to be freely opened and closed. The upper side portion 44 is inserted and polymerized B, and fixed by welding or the like. Further, the lower side portion 42 of the glass frame 38 is inserted and fixed to a door lock bracket 45 located at the middle portion of the glass frame 43, and the lower side portion 46 of the glass frame 43 is connected to the rear portion of the lower side portion 42. I have. The upper side 44 and the lower side of these glass frames 43 have different angles with respect to the lower side 42, and therefore, the upper glass 37 and the lower glass 47 attached to the outside thereof are along the lower side 42. A seam 48 made of an adhesive or the like is formed to change the angle of the glass surface. The glass plates 37 and 47 are mounted on the outer surfaces of the glass frames 38 and 43 with an elastic body such as rubber interposed therebetween, and are fixed to hinges 29 and corners of the glass frame 43 and the like. 50 and 45 parts of the door lock bracket. In the mounting seat 50, a stepped nut 51 and an elastic body 52 fitted on the outer periphery of the mounting hole 49 formed in the glass 37, 47 are fitted to fit the stepped nut 51 and the mounting seat 50. Is fixed with a bolt 53. The peripheral edges of the glasses 37 and 47 with respect to the door lock bracket 45 are fitted and held via rubber seals 54. The outer peripheral edges of the glass 37, 47 project outward beyond the glass frames 38, 43, and a seal damper 55 is attached. When the door is closed, the cabin 21 is closed.
The airtightness is maintained by making contact with the seal receiving edge provided on the side of the frame and the lower edges 39 of the left and right side portions 4 of the roof frame 1 and the like. The front edge 5 of the door lock bracket 45
6, a door lock bracket 45 is provided inside a seal damper 55 attached to the front side edge of the lower glass 47.
A drain passage 59 communicating with the inside of the housing 57 and a drain hole 58 is formed to guide water that has entered the inside of the door lock bracket 45 downward, and drain from a drain hole 60 formed in the seal damper 55 at the lower end. I do.
