摘要： PROBLEM TO BE SOLVED: To provide a needle guard device of a sewing machine which can prevent damage of a needle, such as breaking, by collision of the needle against a needle guide member even if the top of the needle bends largely and which keeps the needle and the needle guide member in contact with each other for a long time to ensure a catch of a needle thread loop by a looper.
SOLUTION: A needle guard member 15 is brought into contact with a needle to guide a needle 9 in the regular moving track position when the needle 9 is made to cooperate with a looper 34 to form a stitch. A needle guard swing mechanism is provided on the needle guard member 15 for causing the needle guard member 15 to swing the needle guard board 13 having the needle guard member 15 horizontally and vertically combinedly to give a horizontal movement along a sewing direction and a vertical movement.
