ことを特徴とするミシンの糸調子装置。 A thread tension shaft supported by the sewing machine and rotated by the operation of a manual operation member, a pair of tension discs at least one of which is slidably supported on the shaft, and a spring means for pressing one tension disc against the other. In a thread tension device that is provided with a thread loosening means that protrudes laterally from the thread tension shaft and prevents the action of the spring means from reaching the tension plate by rotation of the thread tension shaft, the thread tension device is integrated with the thread tension shaft. It consists of an arm that rotates as shown in FIG. A thread tension device for a sewing machine, characterized in that an arm is rotated to a position where a release lever is inactive, where thread loosening is released and tension is activated.
