Since the guide grooves 27 and 37 are tightened and fixed with
By removing the roller 52, the guide groove 27,
Since it can be inserted into and removed from 37,
Adjacent door bodies can be easily connected or separated.

Furthermore, the mounting positions of the mounting bodies 21 and 31 can be regulated by the stepped portions 11a and 12a of the vertical stile 10, and the mounting bodies 21 and
31 can be easily positioned and connected to the vertical stile 10.

Effects of the invention: When the adjacent door bodies are extended, the protrusions of the pair of door wheels and the roller housing overlap, so the gap between the rollers and the guide groove can be closed by the protrusions, and when the door bodies are extended, the door Because there is no relative vertical displacement of the body,
The door body will not rattle or tilt.

Also, fix the mounting part to the guide groove of one door body,
Since the roller storage portion faces the guide groove of the other door body, the distance between the upper and lower frames of adjacent door bodies can be shortened, and the width of the adjacent door bodies in the out-of-plane direction can be reduced.
