PURPOSE: To bring a window closing device into an entire closed condition when a gap is generated caused by vibration in the window closing device equipped with a power window mechanism provided for the cabin. CONSTITUTION: A limit switch 21 detecting the entire closed condition of a front window 17 is provided at the lower side of a front board 11A. Under a condition that no operation signal is outputted by a window closing switch 20, when a detection signal from the limit switch 21 is changed from an entire closed condition over to an open condition, it is thereby judged that the front window is opened, a window closing drive means is driven to the direction that the window is closed, and the gap of the front window 17 is thereby automatically closed. By this constitution, the inside of the cabin 4 is completely isolated from the outside, and the inside of the cabin 4 can thereby be formed into a pleasant space. |
