In the sewing machine, a base end 21 is supported on one side of the feed dog 18 so as to be movable up and down with respect to the head 11 of the sewing machine, and a free end 23 is supported on one side of the feed dog 18.
a first thread cutting blade 19 that extends so as to be located between the feed blade 18 and the thread ring catcher 13, and has a blade portion 28 at the tip facing the vertical movement path of the needle 10; Provided between the first thread cutting blade 19 and the bed 11, for urging the free end side of the first thread cutting blade 19 to a downward position where it does not always come into contact with the lower surface of the feed dog 18. While the biasing means 27, the needle 10, and the feed dog 18 are in the upward stroke, they move from a position away from the first thread cutting blade 19 to approaching the first thread cutting blade 19. After handling the yarn to catch the required yarn,
a second thread cutting blade 39 that cuts the captured thread in cooperation with the first thread cutting blade 19; When the thread loop catcher 13 passes through the inner hook 15 and leaves the outer hook 14, the first thread is prevented from getting entangled with the free end 23 of the first thread cutting blade 19. Fixed on the cutting blade 19 and connected to the feed blade 18 and the thread ring catcher 13
A thread cutting device characterized in that a shielding plate 30 made of a thin plate is disposed between the thread cutting device and the shielding plate 30.
