Abstract
A transporting system with a fire door (100) is provided with: a rail (1) installed within a facility; a transporting carriage (3), whose wheel (4) is set so as to roll over a surface for rolling of the rail; a fire door plate (7) for segmenting a space within the facility in a direction intersecting the rail at a predetermined position of the rail; and a door plate moving device (8) capable of moving the fire door plate from an open position for the transporting carriage to pass through the predetermined position, to a close position for the fire door plate to segment the space. A first cut (1a) is formed obliquely with respect to a width direction of the rail when planarly seen on the surface for rolling, in the rail at the predetermined position. The fire door plate has a shape capable of passing through the first cut when being moved to the close position.
