Abstract

PURPOSE:To obtain mechanical close contact with a simple structure by opening or closing a door main body pin-supported on a chain provided near a door entrance and driven vertically via arms against the door entrance section with only the drive of the chain. CONSTITUTION:A chain 2 is driven by the drive of a drive motor 4 via upper and lower sprockets 1a, 1b, and a door main body 5 is vertically moved via arms 6a, 6b. When the bottom section of the door main body 5 is kept in no contact with a slide roller 12, upper end faces of the arms 6a, 6b are kept horizontal in contact with arm stoppers 7a, 7b by the tare weight of the door main body 5, and the door main body 5 is moved downward. When the lower end of the door main body 5 is brought into contact with the slide roller 12 and the chain 2 is moved downward and loosened, the arms 6a, 6b are inclined to the chain 2 side. A guide roller 10 is moved to the door main body 5 side, and the door main body 5 is closely stuck to the door entrance section.
