Claims

[Scope of Claim for Utility Model Registration] (1) The vertical wall connecting the ceiling and floor is curved so that it is at least half circular,
and a cylindrical workroom having an entrance/exit opened with a set width in the arcuate surface, the entrance/exit can be closed and stored inside near both ends of the standing wall forming the entrance/exit, and is concentric with the standing wall. The outer door and the inner door, which are formed with a curvature of A rotating double-sided vertical cylindrical working room, characterized in that it is configured to be able to travel in different directions, and to form a double closed state with the outer door and the inner door when the entrance/exit is closed. Door opening/closing structure. (2) If the outer door is on the outside, then the inner door is on the inside, so that rack teeth are provided on each of the surfaces that have a front and back relationship with each other, and each of the rack teeth is pivotally supported in a part of the work chamber. 2. The vertical cylinder according to claim 1, further comprising an interlocking mechanism in which the pinion gears are engaged and spanned by an endless chain that provides rotational motion between sprockets attached to the shafts of the respective pinion gears. Opening/closing structure of the rotating double door in the shape work room. (3) If the outer door is on the outside, the inner door is on the inside, so that the rack teeth are formed so that they are front and back to each other, and protrude in opposite directions from the opposite ends of the outer door and the inner door. 2. The vertical cylindrical working chamber according to claim 1, further comprising an interlocking mechanism with a pinion gear of a rotation source meshing with the rack teeth provided relatively inwardly of the respective protruding rack teeth. Rotating double door opening/closing structure. (4) If the outer door is on the outside, then the inner door is on the inside, so that rack teeth are provided on each of the surfaces that have a front and back relationship with each other, and each of the rack teeth is pivotally supported in a part of the work chamber. 2. The vertical column according to claim 1, further comprising an interlocking mechanism that meshes with a driving gear that meshes with a pinion gear and that is coaxial with a rotation axis of the outer door and the inner door for each pinion gear. Opening/closing structure of the rotating double door in the shape work room.
