面５ｅに形成された凸部５ｄに押圧されることになる。Since the presser foot 7 is rotatable by the shaft 8 and is biased by the spring 10, the rack 1 is
The movement of 6b in the direction of arrow A causes the tip 7a to receive a force in a direction of rotating upward about the shaft 8. As a result, the presser foot 7 is in a state in which the lower surface 7b is substantially parallel to the upper surface 5e of the needle plate 5 and the rear end 7c is tilted slightly downward. Therefore, the cloths P and Q are pressed by the rear end 7c and the convex portion 5d formed on the upper surface 5e of the needle plate 5.

When 6 traverses, it is most strongly pressed and pulled just before the needle hole 0. In addition, the dough P and Q are 0 needle holes
Immediately after, the protrusion 5 formed on the upper surface 5e of the needle plate 5
Since the cloth P and the cloth Q are clamped between d and the lower surface 7b of the presser foot 7, the cloth P and the cloth Q are moved in the direction of the arrow A without being displaced or jerked between these two points.

And, immediately after the needle hole 0, the fabrics P and Q have the convex portion 5d formed on the upper surface 5e of the needle plate 5.
Since it is sandwiched between the lower surface 7b of the presser foot 7, the cloth P and the cloth Q can move while being pulled more strongly between these two points. Therefore, the sewing machine needle 4 can be lowered and sewn without causing a shift or a deviation.
