A plurality of rails 22 and 24 to be fitted are formed to cover the upper part of the inner cylinder 4, and the lower part of the rectangular cover part 2 is opened, and the driver's seat 102 ceiling upper surface and the cover part. Consists of a folding windscreen (8) pivotally coupled to the upper front of (2).

This will be described in more detail as follows. As shown in FIG. 1;

The inner cylinder 4 is a rectangular cylinder having an upper portion open and a door 104 installed at the rear thereof, and a hydraulic cylinder 6 having a lifting shaft at an upper end thereof is installed at an inner side of each corner. At this time, the support plate 64 of a predetermined shape is formed on the elevating shaft 62. The hydraulic cylinder 6 is a lifting force is generated by forcibly pushing or pulling the hydraulic oil between the cylinder (not shown) and the piston (not shown) by a known technique.

Further, a plurality of guide grooves 42 having a predetermined length in the longitudinal direction and a cross section of a substantially "c" shape are formed in the outer side surface of each corner and the long side wall of the inner cylinder 4. At this time, a plurality of coupling holes 44 are formed in the four guide grooves 42 formed on the side of the corners of the guide grooves 42 so that the fixing force thereof is more firmly fixed when the cover portion 2 is elevated and fixed to a predetermined height. Fixing pin 50 is fitted to the coupling hole 44 to reinforce.

The cover part 2 is a rectangular cylinder having a lower part open and a door 104 installed at a rear side thereof. The first rail 22 and the second rail 24 are separately formed on the inner side and the long side wall of each corner. The rail 30 is installed. At this time, the first rail 22 has a cross-section having a substantially "T" shape and a length in the longitudinal direction equal to the height of the cylinder, and the second rail 24 is installed at the lower end of the cover part 2. The first rail 22 has the same shape but a shorter length. The third rail 30 is manufactured separately in the same shape as the second rail 24. After the cover part 2 and the inner cylinder 4 are coupled, the second rail 24 is fitted and coupled. The fixing force is provided on the upper part of the guide groove 42 by the bolt 100 so that the supporting force is provided to prevent the cover part 2 from being separated due to excessive lifting operation of the cover part 2 and resistance of wind during driving. .
