摘要： The present invention relates to a lower thread bobbin for a sewing machine able to hold a thread, the bobbin comprising a crescent moon-shaped winding part on which a thread can be wound and a crescent moon-shaped securing part for covering the winding part on which the thread has been wound. The lower thread bobbin for a sewing machine has the advantage of being able to hold a greater amount of a lower thread than the very limited amount of a lower thread that is wound on general conventional bobbins, and so increasing the efficiency of sewing work as the user or sewing machinist does not replace the bobbin frequently.
