PROBLEM TO BE SOLVED: To facilitate attachment of a bolt to a bolt-receiving part. SOLUTION: A bolt is fixed in the bolt-receiving part 30, and a fixing implement fixing an air filter unit to a casing is attached to the bolt. The bolt-receiving part 30 has a bolt hole 32 consisting of a notch a part of which is formed from one end 30A of the bolt-receiving part 30. One end 30A of the bolt-receiving part 30 is folded to the side of the back surface 30C so as to form a pair of rotation-stopping projections 34 and 34. A bolt shaft is inserted into the bolt hole 32 so that the head of the bolt is arranged on the back surface 30C. The bolt is fixed with a nut screwed on the side of the front surface 30D of the bolt-receiving part 30. The head of the bolt is arranged partially between the pair of the rotation-stopping projections 34 and 34. When the nut is screwed with the bolt, the rotation of the bolt is regulated by the rotation-stopping projections 34 and 34. COPYRIGHT: (C)2011,JPO&INPIT |
