ABSTRACT:
The sliding door of this invention substantially comprises a door body and a mechanism which imparts the slide movement and rotating movement to the door body simultaneously. Due to such mechanism, the sliding door can be opened or closed necessitating the considerably smaller operating space compared with conventional slide doors or swinging doors. Such door provides full utilization of the space of a building such as a warehouse.
