Claims

[Scope of utility model registration request]

A plurality of thin plate-like louver pieces each having a rotary shaft protrusion and a rotation guide protrusion arranged side by side on the edge, and a rotary shaft protrusion of each of the plurality of louver pieces in a group of louver rotary shaft holes arranged in a row. At the same time, the rotation guide protrusion of each of the plurality of louver pieces is inserted into the circular arc-shaped louver rotation guide hole group corresponding to the louver rotation shaft hole group, and the plurality of louver pieces are held at a certain angle. A louver support plate is rotatably supported within a range, and rotation guide protrusions of the plurality of louver eight pieces are respectively inserted into a group of shaft holes for interlocking rotation arranged in a row on the outside of the louver support plate. an interlocking plate that interlocks and rotates a plurality of louver pieces in a parallel state; an auxiliary support plate arranged side by side with the louver support plate on a side opposite to the plurality of louver pieces; and an auxiliary support plate arranged between the louver support plate and the auxiliary support plate. A pair of rotary shaft protrusions formed on both sides are inserted into the rotary shaft holes of the louver support plate and the auxiliary support plate, and a pair of interlocking plate driving protrusions formed on the louver support plate side are inserted into the rotational shaft holes of the louver support plate and the auxiliary support plate. A louver device comprising: an auxiliary movable piece that is inserted into an auxiliary movable piece rotating shaft hole to move the interlocking plate; and an operating lever fixed to the auxiliary movable piece.
