PURPOSE:To prevent dust from being sucked into an air-conditioning device for a farm tractor or the like, by forming an air-intake port in the front upper transverse frame of a cabin so that introduced air is led into the air conditioning device through left and right frames, a rear frame and a duct in a roof. CONSTITUTION:A front upper transverse frame 5, a rear upper transverse frame 6, and right and left longitudinal frames are formed in rectangular cylinder shapes, and an outside air intake port 12 is formed in the front upper transverse frame 5 and are communicated with the upper parts of support struts 3, 3, the front end parts of the right and left longitudinal frames and both end openings 13 of the front upper transverse frame 6. Further, a communication hole 17 is formed in the rear upper transverse frame 6 at the center thereof, and is communicated with the rear section of an air-conditioning device 18 through a duct 23 having a lid 23 provided with a handle. with this arrangement in which the outside air inlet port is directed forward, it is possible to prevent dust swirling up from being sucked, thereby it is possible to reduce the clogging of a filter. |
