Claims

[Scope of utility model registration request]

A blind stitch sewing machine in which a plunger is attached to one end of a drive shaft that is supported on a bearing and rotates back and forth in the circumferential direction at a predetermined angle, and that rotates in the circumferential direction together with the drive shaft to press the cloth against the presser foot. In the cloth pressing device described above, the bearing that pivotally supports the other end of the drive shaft is rotatably provided around the pivot in the direction in which the plunger presses the cloth, and the bearing that pivotally supports the other end of the drive shaft is rotatable in the direction in which the plunger presses the cloth. The supporting bearing is guided by a guide and is movable in the pressing direction about the pivot, and the plunger is provided with a spring that biases the plunger in the cloth pressing direction. Features: Fabric pressing device for blind stitch sewing machines.
