To easily move a sliding screen in the horizontal direction by forming the shaft hole of an axle in a case in a long shape in the vertical direction and tiltably forming the shaft hole in an elliptical range in the vertical direction.
An upward and downward long elliptical shaft hole 4 is outward formed by a bar ring 5 on a planar substantially U-shaped inner case 3. An axle 6 is inserted in the shaft hole 4 of the inner case 3, and a tire 8 is rotatably mounted through a bearing bush 7 on the axle 6. Furthermore, the inner case 3 is fitted in a planar substantially U-shaped outer case 2 to form a sash roller 1. The outer case 2 of the sash roller 1 is fixed on a sliding screen with a fixing screw. Thereby since the shaft hole 4 of the inner case 3 supporting the axle 6 is upward and downward long elliptical, the axle 6 can be inclined, the sliding screen can be moved in the horizontal direction from a rail 9 by inclining the tire 8.
