<p>PROBLEM TO BE SOLVED: To facilitate fuel supplying work by attaching a fuel tank to a support frame freely rotated around a lower fulcrum, constituting the fuel tank in the same level of an engine so as to be position-changed and keeping a supply port always directed upward irrespective of the position change of the fuel tank. SOLUTION: For a fuel tank support frame 12, a movable support frame 12A is provided so as to be freely rotated around a front and rear axis XI toward a machine body horizontal side by using its lower end as a fulcrum. A fuel tank 9 is placed in the same level of an engine so as to be rotated by attaching a pair of left and right bands 13 to the upper surface of the movable support frame 12A. For the movable support frame 12A, its side falling posture is regulated by a link 15 and, in its erected position, the end part of an upper frame part 12a in the inside of the machine body is brought into contact with the upper surface of a fixed support frame 12B. The fuel tank 9 includes a fuel supply port 9a obliquely formed in the upper corner part of the inside of the machine body, and the fuel support port 9a is directed upward irrespective of the rotation of the movable support frame 12A.</p> |
