Therefore, even in this position, the operating levers, rods, and other members (not shown) are located below the floor 35, making maintenance work on these members possible. If the cabin 1 is tilted forward as shown by the dotted line in the figure, a larger space is secured above the cylinder case 25, and the front wall 36 of the cabin 1 is also separated from the rear part of the bonnet 37, so that the rear wall 36 and the front wall 36 are separated from each other. This is convenient for work in the vicinity of the wall 36, and since the cabin 1 is first raised in the same position and then tilted forward, the front wall 36 of the cabin 1 is moved against the bonnet 37 during this forward tilting operation. There is no longer any risk of contact with the rear of the vehicle or the fuel tank.
