To provide a structure of a glass sash capable of suppressing a vertical dimension of a bottom rail to a small size, even when a large-sized or bi-layered glass panel is used.SOLUTION: A pair of an outdoor side sash roller 44a and an indoor side sash roller 45a is mounted respectively on both sides in an in-plane direction of a bottom part of an outer bottom rail 27a, so as to be separated from each other in an out-of-plane direction, for movably supporting an outer sash 3a being the glass sash in the in-plane direction relative to a bottom frame 6. An indoor side part of an outdoor side wheel 47a constituting the outdoor side sash roller 44a is disposed below a glass panel 30a, and, an entire indoor side wheel 49a constituting the indoor side sash roller 45a is disposed in a position shifted from the glass panel 30a towards an indoor side. Moreover, a diameter of the indoor side wheel 49a is made larger than the diameter of the outdoor side wheel 47a.SELECTED DRAWING: Figure 8 【課題】大型や複層のガラスパネルを使用した場合にも、下框の上下寸法を小さく抑えることができる、ガラス障子の構造を実現する。【解決手段】ガラス障子である外障子３ａを、下枠６に対して面内方向に移動可能に支持するために、外下框２７ａの下部の面内方向両側部分にそれぞれ、１組の室外側戸車４４ａ及び室内側戸車４５ａを互いに面外方向に離隔した状態で取り付ける。室外側戸車４４ａを構成する室外側車輪４７ａの室内側部を、ガラスパネル３０ａの下方に配置し、かつ、室内側戸車４５ａを構成する室内側車輪４９ａ全体を、ガラスパネル３０ａから室内側に外れた位置に配置する。また、室内側車輪４９ａの直径を室外側車輪４７ａの直径よりも大きくする。【選択図】図８
