Note that caps or packing materials (not shown) different from the waterproof materials 7 and 8 may be fitted in advance to the small openings at the upper and lower ends of the vertical frames 3 and 4 at the factory. Alternatively, a packing part (not shown) may be integrally formed with the lower seal part 7c of the waterproof material 7, and the cap or the packing part may be fitted into the small frame of the vertical frame.

Further, the lower end surfaces of the vertical frames 3 and 4 have a drainage plate 6
Since it is in close contact with the upper seal portion 8c of the waterproof material 8 at both ends of the, the rainwater flowing down the holding portion 2a of the lower frame 2 and the outdoor side surface enters between the lower frame and the inclined portion 6a of the drainage plate. Then, even if the window is moved in the left-right direction when viewed from the front, the rainwater is stopped by the upper seal portion 8c and drained to the outdoor side,
It flows down from the hanging part 6b. Then, since the lower surface of the lower surface waterproof material 12 of the drainage board 6 and the lower seal portions 8b of the waterproof material 8 at both ends of the drainage board are in close contact with the upper end surface of the lower panel LP of the window, rainwater is drained. Intrusion into the outer wall from between the cut plate 6 and the upper end of the lower panel LP is prevented.
