A duct connected to an air-conditioning apparatus includes a portion positioned closer to a side window than a console when viewed from above. A tray is arranged on the console on a side close to the side window, and covers an area above the duct. A lower end of the side window is positioned lower than an upper end of the console positioned on the side close to the side window in terms of height from a floor surface. The tray is positioned on or below an imaginary straight line A-A connecting the upper end to the lower end of the side window, and is not positioned above imaginary straight line A-A. Accordingly, high visibility can be ensured in an obliquely downward direction lateral to an operator while a satisfactory aesthetic appearance of indoor space in a cab is maintained.
