Abstract
A louver device comprises a main body formed of a flexible sheet-like material. A large number of slits are formed in the main body such that the portions between the adjacent slits constitute slats. The louver device also comprises holding/deforming means for shearing at least part of the main body in the direction of the surfaces of the main body. The shearing force applied to the main body serves to twist the end of the slats, thereby slanting the slats.
