Abstract
A bobbin thread cutting device of a sewing machine for cutting a bobbin thread and for temporarily anchoring an end of the cut thread. The bobbin thread cutting device has a cover openably attached to a bed. The cover is formed with a guide groove in which a cutting blade is positioned. A blade edge of the cutting blade and a side edge of the guide groove define an acute-angled portion. A direction in which the bobbin thread is pulled out of the bed through the guide groove intersects a direction in which the bobbin thread extends from a tension generating portion of the bobbin case when the bobbin thread is about to be cut. A leading end of a cut bobbin thread is temporarily anchored at the acute-angled portion.
