PROBLEM TO BE SOLVED: To provide a lattice easily and reliably installed to a window or the like and preventing the fall of an outer frame even when a fixing screw is loosened by aged deterioration. SOLUTION: The lattice 1 has a latching support 6 formed by providing a mounting body 61 stuck to a window frame 71, with upper and lower hooks 62, 62 engaging the outer frame 2 from above. The upper hook 62 is formed, on the upper edge side, with a temporary placing edge part 623 placing an upper latching part 511 of the outer frame 2; an upward fall preventing edge part 624 on the front side of the window frame 71 rather than the temporary placing edge part 623; and a downward slit edge part 621 on the window frame 71 side rather than the temporary placing edge part 623. The lower hook 62 is formed, on the upper edge side, with a non-interfering upper edge part 626 not interfering with a lower latching part 511 of the outer frame 2, and a downward slit edge part 621 on the window frame 71 side rather than the non-interfering upper edge part 626. An internal threaded hole 622 communicating with a fixing hole 513 provided in the outer frame 2 is opened in one or both of the upper and lower hooks 62. COPYRIGHT: (C)2007,JPO&INPIT
