敷居の溝に嵌め込んで走行させることで引戸の開閉を行
うことは周知である。2. Description of the Related Art It is well known that a door roller is attached to a lower end surface of a sliding door, and a wheel is fitted into a groove of a sill for traveling to open and close the sliding door.

【０００３】また、引戸の開閉を更に円滑にするため、
戸車の取り付け位置の調整が行われ、この取り付け位置
の調整には引戸の上下方向と厚さ方向とがある。Also, in order to make opening and closing of the sliding door smoother,
The attachment position of the door roller is adjusted, and the attachment position is adjusted in the vertical direction and the thickness direction of the sliding door.

えることで対処していた。Further, there are conventionally known door rollers capable of adjusting the vertical position of the door, but there are few door rollers capable of adjusting the position in the thickness direction, and generally, a skilled craftsman is required when installing the sliding door. In order to open and close the door smoothly, the door roller was installed by accurately measuring the installation position according to the groove of the sill. In particular, when the door is not properly erected in the thickness direction during use, the door is once removed and the installation position of the door roller is changed in the thickness direction.

2 is moved forward / backward along the side walls 11 of the vehicle. The adjusting plate 37 rotates the traveling body 6 with the support rod 25 as a fulcrum via the engaging groove 20, and is shown by an imaginary line in FIG. Thus, the wheels 4 are moved in the vertical direction. That is, the vertical adjustment screw 36
The vertical position of the wheel 4 is adjusted by turning the wheel with a tool such as a screwdriver.
