PROBLEM TO BE SOLVED: To prevent damage of a threading device and a spreader by preventing their collision. SOLUTION: This threading device 1 includes a threading hook which moves forward to enter an eye of each sewing needle 80a-80e to catch needle thread, and moves rearward with the needle thread being caught to insert the needle thread through the eye, a threading shaft which holds the threading hook, a threading operation mechanism which transmits the movement of the threading shaft to the threading hook to move the threading hook back and forth, an operating member 14 which is operated to move the threading shaft, and a restricting device 16 which moves to tangle a fancy yarn with the needle thread and form an upper fancy stitch, makes the threading operation mechanism inoperable when the spreader mechanism 4 configured to be attachable/detachable relative to a sewing machine body is attached to the sewing machine body, and makes the threading operation mechanism operable when the spreader mechanism is detached from the sewing machine body.
