A presser foot assembly in a sewing machine essentially comprising a presser foot having a catch pin plateau integrally connected to its cambered press plate and a holder which is adapted to be fixed to the body of the sewing machine. The holder has a curved front extension, and this curved front extension has a lateral and longitudinal slot in its bottom to snugly accommodate the catch pin plateau of the press plate, permitting the free inclination of the presser foot about its pivot within so controlled limits that the needle cannot come to contact to the edge of the needle aperture of the press plate.
