A horizontal hook sewing machine is provided with a thread holding mechanism for holding the thread holding mechanism in a predetermined position, and the thread regulating mechanism is attached to a frame-shaped hook provided around the periphery of the horizontal hook and having an inclined portion that comes into contact with the bobbin thread. Thread presser and
The thread presser mechanism is composed of a cam provided on the lower shaft and a contact body that comes into contact with the cam and swings the thread presser, and the thread presser mechanism is configured to include a cam that contacts the bobbin thread and a female mechanism. A horizontal hook sewing machine characterized by comprising a rotating means that is linked to the operation and releases the engagement between the contact body and the cam, and also rotates the thread presser so that the thread is at a predetermined position when cutting the thread.
