シンの糸切り装置。[Scope of claim for utility model registration] A movable blade that is rotatably supported on the machine frame, a fixed blade that has one end fixed to the machine frame and cuts sewing thread by slidingly contacting the movable blade, and a fixed blade that is rotatable on the machine frame. In a thread cutting device for a sewing machine, the thread cutting shaft is connected to a movable blade at one end, and the other end supports a knife driving arm that swings in conjunction with the main shaft of the sewing machine during thread cutting. The knife drive arm is supported on the thread trimming shaft by a pair of tapered parts formed on the thread cutting shaft, and an adjustment screw screwed into the knife driving arm and whose tip abuts on each tapered part. A thread cutting device for a sewing machine, characterized in that the support position of a drive arm is variable, and the initial position of a movable blade relative to a fixed blade is variable.
