とを特徴とするミシンにおひる布送り装置。The root end of the main feed plate fits into the eccentric crank of the upper shaft,
The intermediate portion is attached to the main feeder support rod which rotates around the crankshaft of the feed adjustment slider crank, and the main feeder is attached to the main feeder approximately midway between the main feeder support rod and the root end. The support rod for the sub-feed table, which swings using the support rod pin as a fulcrum, is equipped with a feed dog that feeds the fabric back and forth, and the base of the sub-feed table has its tip secured to the feed plate so as to be slidable back and forth. is rotatably mounted, and the feed adjustment slider crank is slid up and down by the rotation of a transmission shaft rotatably supported on the frame body, and the swinging movement between the sub-feed base support port and the RAD is A cloth feeding device for use in a sewing machine, characterized in that the transmission shaft is provided with a longitudinal feed adjustment crank that changes the amplitude of the cloth feeding stroke of the sub-feed table.
