PROBLEM TO BE SOLVED: To provide a structurally simple and inexpensive device by providing a pair of sashes to slidingly move both edges of door windowpane, guide pulleys arranged in the vicinity of the upper and lower ends of the sashes extending between door panels, a flexible transmitting member extended in an X shape between the guide pulleys, a driving device to drive it in both forward and backward directions and a carrier member to hold the windowpane. SOLUTION: Lower extension parts 52F' and 52R' of sashes 52F and 52R slidably housed with windowpane 18 are arranged between an outer panel and an inner panel under a window opening 16 of a door 10. Respective single guide pulleys 54F, 56F and 54R, 56R are respectively arranged in the vicinity of the upper and lower ends of these lower extension parts 52F' and 52R', and a flexible transmitting member 32 such as a series of rope is extended in an X shape between these. In the flexible transmitting member 32, one end part is fixed to a main driving pulley 28 of a driving device 30, and the other end is fixed to the main driving pulley 28 through the guide pulleys 54F, 56F and 54R, 56R. Therefore, a structurally simple and inexpensive device can be obtained. |
