PROBLEM TO BE SOLVED: To provide a door structure with a door body attached slidably left and right at the gateway of a vinyl greenhouse, which is configured to stabilize the temperature environment in the vinyl greenhouse and at the same time improves assembling workability and decreases production costs by reducing the number of components.SOLUTION: The door structure according to the present invention is characterized in that the door structure with a door body attached slidably left and right at the gateway of the vinyl greenhouse comprises: pipe-shaped rails laid on a lower side of the gateway of the vinyl greenhouse; a guide rail laid on an upper side of the gateway; and a left-and-right slidable door body interposed between the pipe-shaped rails and the guide rail, wherein the door body is formed in a rectangular shape by an upper-side frame, left and right vertical frames, and a lower-side frame, the lower-side frame is structured by a base frame which has an approximately U-shaped cross section with an opening in the lower side, the base frame is provided with a sheet mounting part mountable with a vinyl sheet which is stretched over the door body, and rollers are journaled between inner and outer side plates of the U shape of the base frame in such a manner that the rollers are rollable on the pipe-shaped rails.SELECTED DRAWING: Figure 4 |
