するすくい縫いミシンにおける布の押圧装置。 A movable body is connected to the drive shaft via a vertical movement mechanism, and moves almost perpendicularly to the presser foot when the vertical movement mechanism is operated by the drive shaft. A plunger that presses against the presser foot is attached so as to be freely protrusive and retractable in the moving direction of the movable body, and a stopper is provided that brings a locking portion of the plunger into contact with the movable body to prevent excessive movement of the plunger toward the presser foot side. A cloth pressing device for a blind stitch sewing machine, characterized in that the plunger is connected to a spring that urges the plunger so that a locking portion of the plunger comes into contact with the stopper.
