Therefore, by providing the airtight member 1 including the tongue piece 1b and the plurality of small tongue pieces 1c, 1c at the same time, when the louver sash is closed, rainwater is basically blocked by the tongue piece 1b, and the capillary tube is temporarily used. Even if there is a water leak that has crossed the tongue 1b to the pocket P due to the phenomenon, the pocket P
Serves as a buffer space for the entry of rainwater and prevents further entry. Rainwater that tries to enter the room through the pocket P due to the capillary phenomenon is completely airtight and watertight due to the presence of the small tongue pieces 1c, 1c .... That is, due to the capillarity, rainwater that tries to go under the small tongue piece 1c does not cause the capillary phenomenon itself due to the formation of the plurality of small tongue pieces 1c.
