置。[Scope of Claim for Utility Model Registration] (1) A main feed base equipped with a main feed dog, a differential feed base installed in parallel with the feed base and equipped with an operating feed dog; A vertical movement mechanism that moves the table up and down; a first back-and-forth movement mechanism that moves the main feed table back and forth in conjunction with the main shaft; a second back-and-forth motion mechanism that includes a differential feed crank that swings in a direction and a slider that is slidably attached to the crank, and that is connected to the differential feed base and moves the base back and forth; and the slider. In the sewing machine feeding device, the operating mechanism supports the slider 35, and the slider 35 moves in the radial direction passing through the axis of the forward and backward feed shaft 28. A guide body 38 is provided with support members 37, 39, and 40 that guide the guide so as to be able to swing around a point on the line, and is provided on the feed back and forth shaft 28 so as to be slidable in its radial direction, and Lateral and forward/backward feed axis 28
Operating means 41 and 42 are provided above and are adapted to move the guide body 38 up and down along the differential feed crank 33 when the differential feed crank 33 is in one position of its swing range. A sewing machine feed device featuring: (2) The support member of the guide body 38 is pivoted to the slider 35 and includes a slider 40 having parallel arc-shaped surfaces, and an arc-shaped slider 40 that slidably fits into the parallel surface of the slider 40. A feeding device for a sewing machine according to claim 1, comprising a guide groove 37. (3) The operating means includes a lever shaft 41 provided on the side of the differential feed crank 33 and above the forward and backward feed shaft 28, one end of which is fixed to the lever shaft 41, and the other end of which is pivoted to the guide body 38. A feeding device for a sewing machine as set forth in claim 1, comprising an adjusting lever 42 having a vertical axis.
