The loop () of a needle thread forming the chain seam () is passed through the loop () of a needle thread forming the lock seam () before tightening of stitch is performed, and a loop of the needle thread forming the chain seam located on a downstream side in the sewing direction is passed through the loop of the needle thread forming the upstream chain seam.
