Abstract
A presser foot drive structure of an embroidery machine, by which a vertically movable presser foot for preventing a sheet of cloth to be sewn from rising in a sewing operation is vertically moved inside a sewing head. The presser foot drive structure includes a presser foot drive holder, which is vertically slidable and is mounted on the outer circumference of a needle bar, which is vertically driven; a presser foot drive shaft, which is disposed parallel to the needle bar via the presser foot drive holder; and the presser foot, which is disposed at the lower end of the presser foot drive shaft and vertically reciprocates. It is possible to reduce the stroke of a presser foot so that it is smaller than that of a needle bar, enhance the supporting force for a needle bar, and reduce the shaking of a presser foot.
