PROBLEM TO BE SOLVED: To provide a fitting which can prevent a glass panel fixed in a window frame from slipping out in case of fire. SOLUTION: A round window 1 is formed of: the window frame 2 which has a width piece 21 arranged along an outside surface of an external wall 8, and a depth piece 22 continuously extended from the width piece and arranged on the outside of a room; the glass panel 3 fixed into the window frame; and a slipout prevention device 10 which has a first member 11 and a second member 12 for inhibiting the glass panel from moving toward the outside of the room. The first member has a fixing portion 111 arranged between the width piece and the external wall and fixed to the external wall; and a first connection portion 112 inserted into a through hole 211 formed in the width piece, arranged on the outside of the width piece, and functioning to connect the second member thereto. Thus even if the window frame is melded in case of fire, the first member is fixed to the external wall, and therefore the glass panel is held, to thereby prevent the glass panel from slipping out of the window frame. Further the first connection portion is inserted into the through hole, and therefore the slipout prevention device can be made compact. COPYRIGHT: (C)2008,JPO&INPIT
