One or two or more hanger rollers 3a rotatably provided on a hanger roller hanging bracket 3 can run on an upper rail 2b integrally or separately formed on the base 2. It is necessary to connect the hanger roller hanging metal fitting 3 and the existing manual door 4 by using the main material 5 for hanging. In the same drawing, reference numeral 2c denotes a base cover.

[0003] As shown in the above figure, an angle member made of iron, aluminum or the like having an L-shaped end face is used as the above-mentioned conventional hanging main member 5, which is shown in FIG. As shown in the drawing, after cutting to the width H of the manual door 4, the hanging main member 5 is manually operated with mounting screws 6 using a plurality of required mounting holes 5 b formed in the vertical plate portion 5 a. It is attached to the upper inside front of the door 4. As a result, the horizontal plate 5
c is in the direction away from the manual door 4 to the inside, and extends laterally.

Therefore, the L-shaped suspended main material 5
The horizontal plate 3c for connection of the hanging back plate 3b of the hanger roller hanging metal fitting 3 is placed on the horizontal plate portion 5c of the above, and the fastening is inserted through the adjusting long opening 3d which is long opened in the width direction. The manual door 4 and the hanger roller hanging metal fittings 3 are continuously connected by screwing the bolts 7 into the mounting screw holes 5d which are provided in the horizontal plate portion 5c and only a required number of which are provided therethrough. I have.

Therefore, in the case of using the above-mentioned conventional hanging main material 5, not only a plurality of mounting screw holes 5d in the horizontal plate portion 5c but separated in the longitudinal direction must be formed. The penetration position of the mounting screw hole 5d also requires considerable accuracy, and this kind of work must be performed at the installation site, and therefore, the mounting screw hole 5d must be preliminarily installed at the factory.
Since d cannot be provided, satisfactory results in terms of workability have not been obtained.

[0006] More importantly, the existing manual door 4 is used.
