In some cases, the gap between the lower end of the sliding door and the rail is shielded.

[0003]

Since this conventional shielding member is integral with the sliding door, when the height of the door wheel is adjusted to select an optimal running state, the rail and the lower end of the shielding member are not connected. Are too wide, the shielding effect is impaired, the lower end of the shielding member rubs against the rail, the shielding member is worn, and the opening and closing of the sliding door becomes heavy.

[0004]

An object of the present invention is to move the shielding member up and down in conjunction with the height adjustment of the door wheel so that the distance between the lower end of the shielding member and the rail is always constant and the lower end of the rail and the shielding member as described above. The gap at the lower part of the sliding door can solve problems such as the gap between the sliding door and the door being too wide, and the shielding effect being impaired, the lower end of the shielding member being rubbed against the rail, the shielding member being worn, and the opening and closing of the sliding door being heavy. It is an object to provide a shielding device.

[0005]

According to the present invention, there is provided a gap shielding device at a lower portion of a sliding door, wherein a sliding door having a wheel whose height can be adjusted is attached to a lower portion of a door, and moves up and down in conjunction with an axle of wheels of the sliding door. A shielding member is provided, and a groove is formed in the rail on which the wheel of the door roller rolls so as to fit so that the lower end of the shielding member does not come into contact with the rail in the longitudinal direction of the rail.

[0006]

Since the shielding member moves up and down in conjunction with the axle of the wheel of the door roller, the distance between the lower end of the shielding member and the rail is always constant even when the height of the wheel is adjusted.
