PROBLEM TO BE SOLVED: To expand the range of application of a louver window by improving air-tightness, water-tightness and a crime prevention effect of the louver window. SOLUTION: In the louver window opened and closed by rockings of blades 30, a holder 14 of a tight material 15 where the tight material 15 is mounted is moved parallel to a support shaft 13 of the blade 30, and in a closed state, the blades 30 move the tight material 15 to closely adhere to both side ends 30c of the blade 30. A regulating piece 20 is attached to the holder 14, whereby the rocking angle of the blade 30 is regulated by a regulating piece 20 to perform opening, closing and rocking by interlocking air-tightness with water-tightness.
