ンの糸調子装置の構造。 a pair of thread tension discs for holding the thread on a thread tension shaft fixed to a thread tension base plate fixed to the sewing machine frame; a thread tension spring for applying thread tension pressure between the thread tension discs; In a thread tension device for a sewing machine, the thread tension device is fitted with a spring receiver that transmits the acting force of the spring to the thread tension disc and is moved in a direction to loosen the thread in conjunction with the lifting of the presser foot. An auxiliary spring interposed between the auxiliary spring and the spring receiver, and a disc acting part whose tip end faces the inner surface of the spring receiving side thread tension disc formed on the spring receiver with a small gap in the axial direction. When loosening the thread, the thread tension disc on the spring receiving side is tilted so that the thread insertion side becomes the opening in a state where the thread tension disc on the spring receiving side is partially in contact with the other thread tension disc by cooperation of the disc acting part and the auxiliary spring. A structure of a thread tension device for a sewing machine, characterized in that the other thread tension plate is pressed against the thread tension base plate through the contact portion.
