PURPOSE:To facilitate afterward fitting of an air conditioner by installing an air conditioning unit in a ceiling frame connected with respective upper end parts of both stanchions front and rear in a cabin, and arranging a high pressure pipe and a low pressure pipe communicating refrigerant along the inside of a left side stanchion. CONSTITUTION:A cabin 2 is arranged in the middle part of a vehicle body 1, and formed out of both stanchions front and rear 3, 4, a ceiling 5, a roof 6, etc.. The ceiling 5 is formed by fitting a ceiling member 27 on the underside of a ceiling frame 20. In this case, an air conditioning unit 28 is installed between respective longitudinal frames of the ceiling frame 20, and a high pressure pipe 30 and a low pressure pipe 32 are respectively connected on its inlet ports 29, 31 for high pressure and low pressure. The high pressure pipe 30 passes from the inner part of a cover 17 through the underside of a floor 18 and is connected to the discharge part of a compressor not shown in the figure. The low pressure pipe 32 passes through the inner part of the cover 17, and hereafter is connected to the suction part of the compressor through a filter and a condenser. |
