<p>PURPOSE:To improve the assembly performance of an under cover which is installed so as to cover the lower part between the left and right side frames. CONSTITUTION:A supporting pin 2 is installed on the front side of the lower part inside surfaces of the left and right side frames 1, and a bracket 3 is installed on the rear side. On the front side upper surface of an under cover 5, left and right hooks 6 in pair which can be hooked with the supporting pin 2 are installed, and on the rear side upper surface, the left and right brackets 7 in pair are installed, and the bracket 7 can be fixed by a bolt 9 or s stopper pin. Accordingly, when the under cover 6 is installed for the side frame 1, the under cover 5 is positioned by the hooking of the hook 6 for the supporting pin 2, and the weight charge for an operator can be lightened, and the fixation of the bracket 7 on the cover side for the bracket 7 on the frame side is facilitated.</p> |
