Abstract
An upper feed device is configured to be arranged above a bed of a sewing machine and feed a work cloth. The upper feed device includes a feed portion, a mechanism arrangement portion, and a drive portion. The feed portion includes a first feed mechanism and a second feed mechanism and is configured to feed the work cloth in a feed direction. The first feed mechanism and the second feed mechanism are arranged side by side in a first direction, which is parallel to a top surface of the bed and orthogonal to the feed direction. The mechanism arrangement portion is configured to arrange the first feed mechanism and the second feed mechanism in different positions in a second direction, which is orthogonal to the top surface of the bed. The drive portion is configured to drive the first feed mechanism and the second feed mechanism in synchronization.
