PROBLEM TO BE SOLVED: To provide a window capable of surely preventing insects from invading irrespective of whether an undrawn dimension is set or not. SOLUTION: Insects and dust are prevented from entering to the indoor side through a space at an undrawn part between the second stile 23B of an outdoor side sliding sash 20B and the vertical frame 14 by covering the undrawn part with an auxiliary net sash 40 while a sliding sash 20 is opened. Since the second stile 23B is connected to the vertical frame 14 through the auxiliary net sash 40, the space between the second stile 23B of the outdoor side sliding sash 20B and the fourth stile 23D of an indoor side sliding sash 20A and the space between the fourth stile 23D of the indoor side sliding sash 20A and the vertical frame 14 are not required to be covered independently. Consequently, the number of parts can be reduced. COPYRIGHT: (C)2008,JPO&INPIT
