PROBLEM TO BE SOLVED: To reinforce the rigidity of the lateral side ends on the rotating base end side of a hood by suspending and fixing sub-brackets in lateral positions of a main bracket, fixing the lower end of each sub-bracket to the reverse side of the hood, and supporting the opening and closing of the hood by the cooperation of the main bracket and the sub-brackets. SOLUTION: In a main bracket 15, sub-brackets 18, 18 suspending along the reverse side of the lateral side surface parts of a hood are fixed to the lateral positions of a bracket body 15a in such a manner as to be adjustable of fixing position. A fixed bracket 16 is fixed to the machine body side, and the base end side of a rotating bracket 23 is pivotally connected to a pivotal support part 16a formed at the upper end to constitute a rotating mechanism 17. On the other hand, the lateral sub-brackets 18, 18 fixed to the bracket body 15a of the main bracket 15 are fixed to the reverse side of the lateral side surface parts of the hood. The opening and closing of the rotating base end side of the hood is supported by the cooperation of the main bracket 15 and the sub-brackets 18, 18.
