摘要： Chain-stitch sewing machine includes: a looper provided under a needle plate and having a thread lead-in port and thread lead-out port, the looper being rotationally driven in synchronism with a sewing operation; a plurality of thread feed ports connecting to different thread supply sources; and a connecting member having a thread passage, the connecting member selectively connecting any one of the plurality of thread feed ports to the thread insertion port of the looper via the thread passage. Threading mechanism passes the sewing thread, fed via the thread feed port connected by the connecting member to the thread insertion port of the looper, into the thread insertion port and causes the sewing thread to be taken out via the inserted thread lead-out port of the looper.
