Abstract

PURPOSE:To prevent a driver in a cabin from being interfered by the turning locus of a cross rail for fitting a hood by protruding the upper turning end of a link, interlocked with plural links turned longitudinally at the time of opening/closing an opening part with the hood, upward larger than the turning ends of plural links. CONSTITUTION:When a hydraulic cylinder 36 is contracted, for instance, a first link 8 and a second link 9 are turned backward together with a third link 14, and in association with this, an interlocking link 16 starts its contraction, so that cross rails 17, 18, 25 and 32 are turned toward the rear part of an opening 3 while narrowing spacing as a whole, and thus a hood 35 is folded gradually. In this case, a fourth link 20 and a fifth link 22 are interlocked with the first link 8, the second link 9 and the third link 14, and the upper turning end of the fifth link 22 is protruded upward larger than the turning ends of the first and second links 8, 9. The turning locus 38 of the second intermediate cross rail 25 supported at the upper turning end of the fifth link 22 is also positioned above. This heightens the action freedom of a driver in a cabin 2.
