PROBLEM TO BE SOLVED: To provide an air outlet structure of a cabin for blowing air-conditioning air to the inside of the cabin, capable of adjusting the air volume of air-conditioning air blown out from an air outlet and achieving high resistance to dust invasion from the air outlet.SOLUTION: An air outlet structure of a cabin includes a cloth 11 for covering an air outlet 33 and is configured to blow out air-conditioning air through the cloth 11. The cloth 11 is structured so as to change air permeability with expansion/contraction thereof. The expansion/contraction state of the cloth 11 is changed by an expansion/contraction state changing means 41 for changing the expansion/contraction state of the cloth 11 so that the air volume of air-conditioning air from the air outlet 33 can be adjusted. |
