Here, grooves 5a, 9a which are slidably fitted along the lower rail 7 are formed in the lower horizontal frame 5 and the slider 9 so as to communicate with each other, and the groove 5a of the lower horizontal frame 5 is formed. Since the upper bottom is formed at a position higher than the upper bottom of the groove 9a of the slider 9, the stopper 13 allows the slider 9 of one of the vertical frames 4 to freely move the lower rail 7 when the fixed door 2A slides. After coming off from the end 7b, the groove 5a of the lower horizontal frame 5 slides and is guided by the stopper 13, and after being pulled out by a certain size, the other vertical frame (the base end side of the lower rail 7). When the slider provided on the lower surface of the vertical frame abuts against the stopper 13, the outer frame 3 cannot be further pulled out. In FIG. 8B, reference numeral 25 denotes a rail fixing hole, and a screw 2 inserted through the rail fixing hole 25 is used.
The lower rail 7 can be fixed to the lower floor 40 by screwing the 4 into the lower floor 40 of the entrance opening 1.

The stopper 13 projecting at an arbitrary position on the upper surface 7a of the lower rail 7 functions to guide the lower horizontal frame 5 when the fixed door 2A slides, and the fixed door 2A is moved downward. By acting to prevent the outer peripheral frame 3 from slipping out when the rail 7 slides out of the free end 7b, the lower rail 7 and the fixed door 2A can be easily cleaned.
