たことを特徴とするミシンの送り量調節装置。[Scope of Claim for Utility Model Registration] A feed rod that moves up and down in conjunction with the upper shaft via a cam mechanism, a frame that pivotally supports the lower end of the feed rod at one end, one end that is pivotally supported in the center of the frame, and the other end that is pivotally supported at one end. A link that is pivotally supported by a horizontal feed arm that fits a horizontal feed shaft that drives the feed dog in a predetermined direction, a slider that is movably fitted to a moving shaft provided on the frame, and one end of which is connected to the slider. The feed rod is supported by a rotary base, and the other end is fixed to a ball screw that moves on a ball screw by the rotation of a motor. A feed rate adjusting device for a sewing machine, characterized in that a pivot point between a slider and a rotating base, which is a center of rotation of a frame that rotates reciprocatingly, is variable in the direction of the moving axis.
