ミシンにおける切断糸案内機構。A clutch body that is rotatably supported on the machine frame and has a cam body that is loosely fitted onto the hook shaft so that it can be engaged and detached from the hook shaft, and a hook that can be rotated on the machine frame. The drive arm is supported by the cam body, one end is engaged with the clutch body, and the other end is rotatably supported on the machine frame to press the bobbin and connected to the bobbin holder, and fixed to the machine frame in relation to the rotation of the cam body. The movable blade ") 9, 7 O, □ 9 O I", which slides into fixed force and cuts the bobbin thread and needle thread. When the movable blade 9, 7 O and □ 9 O I move, the bobbin presser catches the needle thread when cutting the thread. A cutting thread guide mechanism in a thread cutting sewing machine comprising a single drive means that rotates a drive arm that applies tension to needle thread and presses a bobbin.
