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

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.

A louver device which uses a sheet-like material, comprising: a main body formed of a flexible and deformable sheet-like material, said sheet-like main body having opposite main surfaces and opposing end portions, said sheet-like main body having a plurality of slits therein, said slits being parallel to a given line and extending from the vicinity of each of said end portions toward the other of said end portions, with said slits having their respective ends bent in opposite angles from being parallel to said given line, the portions of said sheet-like main body which are located between said slits serving as respective slats; and holding and deforming means coupled to said sheet-like main body for supporting and holding said sheet-like main body in a predetermined shape, and including a support means and shearing means for shearing at least part of said sheet-like main body substantially in the direction of the plane of said opposite main surfaces of said sheet-like main body, said shearing means including: (1) respective frame members attached to each of said end portions of said sheet-like main body, and (2) means for moving at least one of said frame members relative to said support means for shearing and deforming said sheet-like main body to cause substantially all of said slats of said sheet-like main body to deform and to tilt or rotate relative to said end portions of said sheet-like main body and with respect to the direction of said plane of said opposite main surfaces of said sheet-like main body due to said movement of said frame members.
