Abstract
An upper decoration mechanism and a sewing machine without requiring an operation of detaching the upper decoration mechanism from the sewing machine without reducing workability even when performing a double chain stitch not using a decoration thread. The upper decoration mechanism provided on a sewing machine includes an expansion retraction mechanism configured to switch a spreader between an expanded state where the spreader cooperates with needles for performing an upper decoration sewing and a retracted state where the spreader is separated from the needles.
