Description of the Related Art In sewing by a sewing machine, sewing cloth supplied on a sewing machine bed is clamped around a needle drop position by a presser foot suspended from a sewing machine arm, and is generally built in the sewing machine bed. The sewing is performed by feeding the sewn cloth with the feed dog. The feed dog is connected to a main shaft inside the sewing machine arm via a known feed mechanism, and performs a predetermined feed operation interlocked with the operation of each part of the sewing machine, specifically, a length in a substantially vertical plane along the feed direction. Perform a circular motion,
Protruding above the sewing machine bed at the top of this motion trajectory,
At the time of projection, the sewing cloth is pressed between the presser foot and the lower surface to apply a feeding force.
