ている。That is, the presser foot swinging device is loosely fitted to the vertical needle bar sleeve 1 and freely swings up and down around the first swing shaft 2 by the horizontal first swing shaft 2. The swinging piece 3 is attached, a cloth foot 4 is provided at the lower end, and a ring 5 is provided at an upper and lower middle part. The swinging piece 3 is mounted on the swinging piece 3 at right angles to the first swinging piece 2. A swing lever 7 pivotally supported at its upper end by a second swing shaft 6 provided so as to be horizontal in the state and swingably movable back and forth and left and right, and a feed lever 8 using a horizontal pin 9 as a fulcrum. The feed lever 8 is rotatably held so that the lower end 8a of the feed lever 8 is locked between the ring 5 and the receiver 10 rotatably fitted to the ring 5 and the receiver 10
Is movably fitted along the guide hole 10a in the diametrical direction of the ring 5 and is rotated by the rotation of the feed lever 8 about the pin 9 as a fulcrum. A rotary member 11 for moving the feed lever 8 in the diameter direction thereof, and pressing the upper end 8b of the feed lever 8 to move the feed lever 8 to the pin 9
And a cam member 12 for rotating the needle bar sleeve 1 around the fulcrum. The rotating member 11 rotates the needle bar sleeve 1 in the same direction and at the same speed as the needle bar sleeve 1 so that the gear 13 and the intermediate gear 14, and The cam member 12 is mounted on the rotating shaft 16 so as to be movable up and down and to rotate together with the rotating shaft 16. .

When the needle bar sleeve 1 is rotated via the bevel gears 17 and the bevel gears 18 and 19, the rotating member 11 and the cam member 12 rotate together with the rotating shaft 16 in conjunction therewith, and the up-and-down mechanism (not shown) When the cam member 12 is depressed by the operation, the feed lever 8 rotates clockwise in FIG. 5 around the pin 9 and moves the ring 5 to the left to move the swing lever 7 about the second swing shaft 6. It is structured to swing to the left. The state of FIG.
Is rotated 90 degrees and the feed lever 8 is moved toward or toward the rotary shaft 16, the swing lever 7 swings about the first swing shaft 2 in a direction perpendicular to the plane of the drawing. The swing piece 3 is loosely fitted to the needle bar sleeve 1.

造が複雑、かつ大形になるといった問題点もある。However, in the above-described conventional structure, the swing lever 7 which can swing back and forth and right and left with respect to the needle bar sleeve 1 is provided at a position which is largely deviated laterally from the center line of the needle bar sleeve 1. In order to swing by 5 and rotating member 11, etc.
The amount of movement of the cloth moved by the cloth presser 4 is not the same in all directions of 360 degrees, and slightly varies depending on the direction, so that a completely uniform seam cannot be obtained. Therefore, when embroidering a fine pattern, a sewing manufacturer must correct the difference in the feed direction, and the operation requires skill. Further, since it is impossible to reduce the backlash of the gears 13, 14, 15 to zero, the accuracy of following the cloth feeding direction is reduced due to the backlash, and also in this respect, embroidery of a fine pattern is impeded. Furthermore, the gears 13, 14, 15 and the rotating shaft 1
6 and the need for additional members such as bearings, there is also a problem that the overall structure is complicated and large.

とした。In order to achieve the above object, the present invention provides a needle bar sleeve which is swingable up and down around the first swing shaft by a first horizontal swing shaft loosely fitted to a vertical needle bar sleeve. An attached swing piece, a cloth presser at a lower end, and a ring at upper and lower intermediate portions, respectively, are provided with a ring at right angles to the first swing axis. A swinging lever pivotally supported at its upper end by a second swinging shaft provided so as to swing back and forth and left and right, and a feed lever rotatably around a horizontal pin as a fulcrum. One end of the lever is engaged with the ring, and is inserted into the ring so as to be rotatable in the circumferential direction of the ring and relatively movably in the diameter direction of the ring. A rotating member for moving the ring in the diameter direction by movement, and the other end of the feed lever And a cam member for pressing the feed lever to rotate the feed lever about a pin as a fulcrum, wherein the rotating member is fixed to the needle bar sleeve by fixing the rotating member to the needle bar sleeve. The rod sleeve is provided so as to be movable in the axial direction of the needle bar sleeve.

る。The rotating member fitted and fixed integrally with the needle bar sleeve rotates completely integrally with the needle bar sleeve. For this reason,
The tracking accuracy in the cloth feeding direction is not impaired. Also,
The cam member moves along the needle bar sleeve to rotate the feed lever about the pin as a fulcrum, and swings the swing lever about the swing axis via the ring. Since the rotating member is attached to the needle bar sleeve as described above, the moving amount of the cloth by the cloth presser does not differ depending on the direction, and is the same in all directions of 360 degrees. Therefore, the pattern can be embroidered precisely without correcting the difference in the feeding direction.
