PURPOSE: To precisely adjust the swiveling at hood opening/closing in a specified swiveling area by way of a lever unit. CONSTITUTION: Two end walls 13 and 14 of a hood 4 form an acute angle while extending along two parallel oblique planes x-x, y-y, and limit edges 30 and 31 at the lower part of the end wall is allowed to move in a gap 15 where a driver cab 3 and a tank 6 overlap each other along a front wall 6a of the tank 6, by way of a lever unit. Here, the limit edges 30 and 31 move in a straight section A along the oblique plane x-x, y-y. |
