Claims

[Claims for Utility Model Registration] A sewing machine equipped with a feed dog 10 for imparting feed to a work cloth on a work cloth support surface, comprising a manual operation member 30, and based on the operation of the manual operation member 30,
A feed adjustment device (24, 16, etc.) for changing and setting the cloth feed amount by the feed dog 10, and a feed adjustment device (24, 16, etc.) that is rotated according to the cloth feed amount set by the feed adjustment device (24, 16, etc.). , an operating shaft 34 whose one end projects outside the sewing machine frame 1; and a first operating shaft 34 connected to the operating shaft 34 in order to rotate the operating shaft 34 and change the set cloth feed amount. a driving means 38; and an engaging member 4 provided at the outer end of the operating shaft 34.
2, a stopper member 44 displaceably provided on the outer surface of the sewing machine frame 1 within the rotation locus of the engaging member 42, and a stopper member 44 for displacing the stopper member 44 to a desired position. and a second driving means 46, based on the feed change signal, the second driving means 4
After the stopper member 44 has been moved to a required position by 6, when the actuating shaft 34 is rotated by the first driving means 38, the engagement between the engaging member 42 and the stopper member 44 causes the A feed changing device for a sewing machine, characterized in that it is configured to restrict rotation of an operating shaft 34.
