A round window can be assembled in the state. Thereby, the common window frame main body 20 can be used for both the round window 1 with the drop-off prevention function and the round window without the drop-off prevention function. Therefore, since the through hole 211 is not formed in the case of a round window without a drop-off preventing function, it is not necessary to close the through hole 211 with an airtight material or the like, and the manufacturing cost can be reduced. Further, by simply forming the through-hole 211 through the groove 213, a window without a drop-off prevention function can be easily made into a window having a drop-off prevention function (fire-proof specification window), so there is no initial drop-off prevention function. Even when a member is carried to a building site as a window, it is possible to change to a window having a drop-off preventing function at the building site.

(9) When the first member 11 and the second member 12 are connected, the sealing member 13 is opened by the bent portions 125 and 126 provided at the ends of the leg portions 123 and 124 of the second connecting portion 121. Since it is pressed by the recessed part 212 of the frame main body 20, the through-hole 211 can be reliably obstruct | occluded by the sealing member 13, and the airtightness and watertightness of indoors and outdoors can be maintained.
