Since a gap that is open on one side and serves as the upper thread restraint part is formed between the upper thread U and the elastic member 17, the upper thread U can be easily inserted from the side into this gap and the upper thread U can be easily inserted into the upper thread restraint member. In addition to simplifying the thread insertion operation, the upper and lower thread guide members 6 guide the upper and lower thread U passing through the gap.
This has the effect of reliably allowing the upper thread to pass through a predetermined position within the gap and reliably preventing errors in stopping the upper thread U.
