PROBLEM TO BE SOLVED: To provide a construction machine capable of improving yield of a fan shroud having a bell mouth shape and reducing its cost.SOLUTION: A fan shroud 22 comprises: a fixed frame member 23 fixed to a heat exchanger 19; a fan ring 24 attached to the fixed frame member 23; and L-shaped ring 25 fixed to the fan ring 24. The L-shaped ring 25 is constituted by an annular fixing plate 25A formed as a cylinder body having L-shaped section by applying a rolling work against L-shaped plate in which a strip-like plate member is bent into L-shape, with its outer diameter side 25A1 being fixed to an opening end 24C of the fan ring 24 and its inner diameter side 25A2 being extended toward a cooling fan 20, and a bent plate part 25B bent from the inner diameter side 25A2 of the fixing plate 25A in a longitudinal direction. This configuration causes yield to be improved, so that it enables a manufacturing cost to be reduced. |
