The door rail 7a interferes with the rear rail 5b by setting the dimensions such that the vertical distance H between the front rail 5a and the rear rail 5b is slightly larger than the depth of the groove 26 of the door rail 7a guided by the rear rail 5b. The front rail 5a when the door roller 7b travels on the inclined portion 12b of the rear rail 5b.
Since the vehicle is run so as not to interfere with the rail 11, the installation space of the rail portion 5 in the blind 11 can be made smaller than that of the conventional one, and the size of the blind 11 in the attaching direction and the prospective direction can be made smaller than that of the conventional one. And can be made smaller,
The indoor side can be made airtight.

という効果がある。As described in detail above, according to the airtight automatic door of the present invention, the horizontal gap between the front rail and the rear rail is slightly larger than the thickness of the brim of the door roller guided by the front rail. Since the vertical gap between the front rail and the rear rail is set to be slightly larger than the depth of the groove of the door roller guided by the rear rail, the rail portion can be installed in a seamless manner. The space is smaller than that of the conventional one, and there is an effect that it is possible to achieve a compact size reduction.
