PROBLEM TO BE SOLVED: To inhibit dust and dirt from accumulating on the rails in a sewing frame driver in which a driver frame is arranged along a sewing frame and a rail of the driving frame is rotatably connected by putting the rail between rollers of the sewing frame. SOLUTION: A driving frame 20 is arranged along the sewing frame 10, a sewing frame side face 24 and a driving frame side face 25 of the rail 22 of the driving frame 20 are held with a sewing frame side roller 34 and a driving frame side roller 35 whereby sewing frame 10 and the driving frame 20 are connected so as to permit the sewing frame 10 and the driving frame 20 to relatively move in the longitudinal direction but not permit in the perpendicular direction. In this sewing frame driver, the rail 22 is set below a top board 21 of the driving frame 20. The sewing frame side roller 34 is provided at the sewing frame 10 and the base plate 41 which can extend over the lower part of the rail 22 below the top board 21 and the driving frame side roller 44 is provided at the extension end.
