Therefore, regardless of the thickness of the sliding door, it is sufficient to mount the door on the center line of the lower frame. In the case of a difference door, the height of the door wheel can be adjusted with a conventional sash door, but there is no function to shift the wheel to the left and right, so if it is mounted on the center line of the lower frame, it will be parallel depending on the thickness of the sliding door. There is a problem that the sliding door is rubbed with the sliding door, so that the thickness of the sliding door must be considered in advance to form the engraving hole of the door roller, which is inconvenient.

[0005]

The object of the present invention is not only to adjust the height of the wheels, but also to
It is an object of the present invention to provide an adjustable door roller capable of shifting the wheels to the left and right even after the door roller is mounted, so that the friction between the lower parts of the sliding doors can be eliminated.

[0006]

According to the present invention, there is provided an adjustable door roller, in which a wheel frame pivotally supported by a pin is pivotally supported by a pin in a door roller case so as to be vertically swingable. Slidably in the front-rear direction by screwing a screw provided so that the head is exposed from the front plate of the door case, and a part of the wheel frame abuts to prevent the wheel frame from swinging. And the wheel frame is configured so that the head can slide left and right through a cam by rotation of a screw exposed from a front plate of the door case.

[0007]

When the screw is rotated, the wheel frame moves left and right by the action of the cam, thereby preventing the lower portions of the sliding door from rubbing.
