置。[Claims for Utility Model Registration] A horizontal feed rod that connects a tip part that swings as the sewing machine main shaft rotates to a pin of a first square piece; It consists of a feed lever, and a main feed swinging body whose one end is pivotally supported by the tip of the main feed lever and whose other end is connected to the main feed table to reciprocate the main feed table in the horizontal direction, and is equipped with a main feed adjustment mechanism. a main feed mechanism; one end is pivotally supported at the tip of the main feed lever together with a main feed swinging body via a sub-feed lever, and the other end is connected to a sub-feed table to horizontally reciprocate on this sub-feed table. It consists of a sub-feed arm to be moved, and a second square piece that is slidably fitted into a through groove formed in the sub-feed arm and serves as the center of reciprocating swing of the sub-feed arm, and is used to adjust the sub-feed. The main feed adjustment mechanism includes a swing shaft rotated by a main feed adjustment lever, and a groove fixed to the swing shaft to insert the first square piece. and a main feed adjuster that is slidably supported, and the sub-feed adjustment mechanism includes a sub-feed swing shaft that is rotated by a sub-feed adjustment lever, and a link that is rotated by the sub-feed swing shaft. and a drive lever that rotates via a mechanism and appropriately moves the second corner piece position, which is pivotally supported at the rotating end, within the through groove of the sub-feed arm. Dynamic feed device.
