る。Therefore, the roller 4a movably provided along the elongated hole 8 on one side of the slide plate 1 has its roller support shaft 6 pressed by the spring member 9, and always approaches the rail surface 3a on one side of the guide rail 2. Therefore, if the nut 7 of the fixing member is loosened and the roller support shaft 6 is temporarily fixed to the extent that it can move, the slide plate 1 is attached to the guide rail 2. Each roller 4 is moved by the elastic force of the spring member 9.
a and 4b abut against the rail surfaces 3a and 3b, respectively, without any gaps.
そこでナツトγを緊締すれば、各ローラ４ａ、４ｂは適
正な位置でレール面３ａ。Then, by tightening the nut γ, each roller 4a, 4b will be in the proper position on the rail surface 3a.
３ｂに当接した状態でスライド板１に取付けられたこと
となる。This means that it is attached to the slide plate 1 in a state where it is in contact with 3b.

されることとなり、極めて便利である。As described above, according to the device of the present invention, the roller 4a provided on the slide plate 1 is given a tendency to move in the direction of contacting the rail surface 3a by the elastic force of the spring member 90 when the roller 4a is in a movable temporarily fixed state. Instead, if the slide plate 1 is attached to the guide rail 2, each roller 4a, 4b will automatically move to the rail surface 3a.
, 3b without any gaps, there is no need for any positioning adjustment when installing the slide plate roller, and anyone can easily perform the installation work with a certain degree of accuracy. Even when the rollers and the like are worn out over time and need to be readjusted, once the nuts and the like are loosened and then re-fastened, they will be automatically positioned and fixed, which is extremely convenient.
