置。[Scope of Claim for Utility Model Registration] To provide a feed dog that imparts a feed motion to the work cloth in synchronization with the vertical reciprocating movement of the sewing needle, and a feed table that holds the feed dog in the forward and backward direction. a horizontal feed arm that swings around a horizontal feed shaft installed in the lower arm of the sewing machine, and a lower shaft that is installed in the lower arm parallel to the horizontal feed shaft and rotates as the main shaft of the sewing machine rotates. , a first cam surface that generates a vertical feed movement that causes the feed dog to protrude and retract from the sewing machine bed surface, and a second cam surface that causes the feed dog to sink with respect to the sewing machine bed surface, and a first cam surface that causes the feed dog to sink relative to the sewing machine bed surface; a vertical feed cam that is slidable in the axial direction of the lower shaft and rotates together with the lower shaft so that one of the cams can selectively engage the feed base or a member operatively connected thereto;
In the sewing machine, the sewing machine includes an operating member that can be manually operated for slidingly displacing the vertical feed cam in the axial direction of the lower shaft, wherein the operating member is slidably mounted on the horizontal feed shaft, and the lower arm an operating end extending outward from an opening drilled in the operating member; an operating engagement portion that engages with the vertical feeding cam for slidingly displacing the vertical feeding cam; and holding the operating position of the operating member. A feeding device for a sewing machine, characterized in that an elastic holding end that elastically engages with a locking portion formed in the lower arm is formed integrally with the operating member.
