ある。[Prior art] As disclosed in Japanese Utility Model Application Publication No. 56-122621,
When the intake duct is fixed to the rear wall of the cab (driver's cab), the pulsation of the intake air causes the cab panel to vibrate, increasing indoor noise. In order to effectively absorb the vibrations of the intake duct, it is preferable to insert a soft vibration-proof rubber into the attachment part of the intake duct, but in this case, there are problems with the strength and durability of the vibration-proof rubber.
