ABSTRACT:
In a presser foot and a sewing machine according to the present invention, a guide hole is formed in a presser leg to which a fixed knife is attached, so as to passing through the presser leg up and down, and a knife holder is fitted and held to the guide hole. The fixed knife is inserted to a retention groove provided in a peripheral surface of the knife holder through a window hole provided in the presser leg, and is fixed by fastening a stop screw. A position of the fixed knife is adjusted in a vertical direction by moving the knife holder in the vertical direction along the guide hole and fastening the stop screw at an appropriate position, thereby changing a cut position of ends of fabrics and changing an overlapped width of the fabrics at a time of seaming.
