Claims (1)

[Claims for Utility Model Registration] A feed table 4 which is placed on a table 2 whose upper surface is a support surface for the work cloth K and is movable back and forth in one direction by a first driving means 9; The workpiece cloth holder 19 is supported by a second driving means 24 and is movable back and forth in the other direction X orthogonal to the moving direction Y of the feed table 4, and the workpiece cloth holder 19 is synchronized with the vertical movement of the needle. In a work cloth feeding device of a sewing machine which forms stitches on a work cloth K on a work cloth holder 19 by movement, the table 2 has a rotating shaft extending in a direction X orthogonal to the moving direction Y of the feed table 4. A winding drum 7 is fixed to each end of the rotating shaft 5, and one end of a pair of wires 13 wound around both drums 7 is attached to the feed table 4 at one end on the Y side of the moving direction. A work cloth feed device for a sewing machine, characterized in that the work cloth feed device for a sewing machine is connected to one end of the feed table 4 through a pulley 12, and the other end is connected to the other side of the feed table 4 in the moving direction Y side.
