Although not shown, when a right foot switch or the like is used to send a presser foot signal, the air cylinder (9) is activated and the rear end of the presser foot lever (7) is activated via the joint (11) and the bottle (12). Pushed in the direction of the arrow. Presser foot lever (7)
When the rear end of the presser lever (7) is pushed to the left, the presser lever (7) rotates about the stepped pin (8) (see Fig. 3). Then, using the guide plate (25) fixed to the presser frame (1) as a guide, the presser frame mounting plate (31) descends while being rolled and supported by the balls (34). As a result, the presser frame (4) fixed to the presser frame mounting plate (31) is attached to the sewing material (22).
is pressed and held on the feed plate (16).

A thread removal signal is transmitted, and the cut upper thread is removed. After the thread is wiped off, the left and right presser foot switches are turned OFF, the driving force of both air cylinders (9) is released, and the presser foot lever (7) is moved clockwise by the spring built into the cylinder (9) and the return spring (15). rotate in the direction. As a result, presser frame mounting plates (2), (3) and presser frames (4), (5)
increases, and one cycle of the sewing operation is completed.

もある。[Effects of the Invention] As described above, according to the present invention, a presser device is constructed in which a rolling bearing is arranged in a sliding portion for raising and lowering a presser frame. As a result, the pressing and releasing operations of the presser device become smooth, and the presser frame moves up and down smoothly when the presser switch is turned on and off. For this reason, even when a sewing product is held at the end of a large presser frame, the presser frame mounting plate (3
1) and (32) can rise without faltering, eliminating the risk of failure. Furthermore, since the sliding portion moves up and down smoothly using rolling bearings, a return spring with a weak spring force can be used, which has the advantage that the material cost of the presser device can be constructed at low cost.
