ている。As described above, according to the present invention, the control tower E is formed into a substantially "L" shape in a side view, and the cover body 35 is provided on the symmetrical frame body F which is arched in a front view. , Gripping the horizontally long posture part of the upper part of the frame body F with the grip part 2
The rod-shaped frame body F is used by connecting the lower end portion to the step frame 15A, and the upper and lower parts of the left and right members constituting the frame body F are closed. By virtue of the above, and the reinforcing action of the cover body 35, the control tower E becomes lightweight and has high strength, and moreover, the internal space can be maintained wider than that in which the frame is arranged inside. In particular, since the fixing portion 35A constituting the cover body 35 is welded and fixed to the column portion 32 of the frame body F, distortion of the frame body F is suppressed,
The cover body 35 protects the support portion G and the operating portion H of the control lever 23, and the detachable portion 35B at the front portion of the cover body 35 is removed to facilitate the internal inspection and maintenance.
