Next, the adjusting operation of the embodiment will be described.

When the lower edge of the door body 4 comes into contact with the floor or the ground of a building (not shown), there is a possibility that the movement of the door body 4 may be obstructed or the lower end of the door body 4 may be damaged, or In the case where a gap is opened because the frontage of the object or the lower end edge of the opening of the furniture cannot be closed, the door body 4 is moved upward or downward with respect to the guide rail 2 for adjustment.

That is, when it is desired to move the adjuster 18 of the vertical adjustment means 25 in a predetermined direction, for example, to move the door body 4 upward, the adjuster 18 is rotated clockwise to move the door body 4 downward. , The adjuster 18 is rotated counterclockwise. By the rotation of the adjuster 18, for example, by rotating the adjuster 18 clockwise, the movable element 21 moves in a direction approaching the end plate 6b of the case body 6, and by rotating the movable element 21 counterclockwise, the movable element 21 is rotated. It moves in a direction away from the end plate 6b.

When the moving member 21 is moved, the position adjusting body 50 in which the locking claw 24, which is the upper end portion of the moving member 21, is engaged with the notch 54 is moved along the shaft of the moving member 21 along the moving direction. It rotates around 45 as a central axis. That is, for example,
When the member 21 is moved in a direction approaching the end plate 6b of the case body 6, the end plate portion 50b of the position adjusting member 50 is rotated so as to approach the end plate 6b, and the moving element 21 moves away from the end plate 6b. When moved in the direction, the end plate portion 50b of the position adjusting body 50 rotates in a direction away from the end plate 6b. Then, by the rotation of the position adjusting body 50, the connecting shaft 52 for connecting the traveling means 60 to the position adjusting body 50 is guided by the bearing groove 47 and moves vertically, that is, the end plate 50b of the position adjusting body 50 is moved. By rotating so as to approach the end plate 6b, the connecting shaft 52 moves toward the bottom 6c of the case body 6 below, and the end plate portion 50b of the position adjusting body 50 rotates in a direction away from the end plate 6b. Then, the connecting shaft 52 moves toward the upper opening 6d of the case body 6.
