レバー４２とを有するミシンの送り装置。(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 a differential feed dog, and a vertical motion that moves both feed bases up and down in conjunction with the main shaft. a first back-and-forth movement mechanism that moves the main feed table back and forth in conjunction with the main shaft;
A differential feed crank that swings in conjunction with the main shaft, a slider that is slidably attached to the crank, and a link mechanism that connects the slider and the differential feeder, and a second mechanism that moves the differential feeder back and forth. In a sewing machine feeding device having a forward and backward movement mechanism and an operating mechanism for moving the slider along a differentially feeding crank, the operating mechanism is slidably and rotatably fitted to the forward and backward feed shaft 28, and the slider 3 is slidably and rotatably fitted into the operating mechanism.
The slider 40 pivoted on the feed shaft 28 swings in the front-rear direction with a guide body 38 that engages with the slider 40 so that it can perform an arcuate motion centered on a point on a radial line passing through the axis of the forward-rear shaft 28. When the differential feed crank 33 is located at the center of swing, it is rotated around the axis coincident with the center of curvature by the operation of the manual operation member 4"4, and the free end is pivoted to the guide body.
