Abstract

The presser foot device of a sewing machine comprises a presser foot 2, a tension mechanism 3 disposed on the presser foot 2 and having a presser member 6 which is adjustably movable back and forth, a guide member 4 provided at a tip end portion of the presser foot 2, wherein a given gap .DELTA. is formed between the presser member 6 of the tension mechanism 3 and the guide member 4, and wherein a belt-shaped rubber member 8 supplied toward a needle penetration point N of the presser foot 2 is passed through the given gap .DELTA., thereby giving a given tension to the belt-shaped rubber member 8. As a result, it is possible to provide a presser foot device of a sewing machine capable of easily, stably and variably setting tension applied to a belt-shaped rubber member, thereby improving the quality of the sewn product and to improve the operability of mounting the belt-shaped rubber member therein by ensuring a large opening space.
