摘要： A zigzag width range setting apparatus 9 sets a minimum value and a maximum value of a zigzag width of a needle 62. When the sewing machine is in operation, if the minimum value of the zigzag width preset by the zigzag width range setting apparatus 9 is higher than 0, a zigzag action is performed in a minimum zigzag width at no operation of a knee lifter 2 (an amount of operation of zero), and if the minimum value is 0, the zigzag width of the needle 62 is 0 at zero amount of operation of the knee lifter 2, that is the zigzag action is not performed, and stitching is performed by moving the needle 62 widthwise in accordance with the amount of operation of the knee lifter 2. If the maximum value is changed by the zigzag width range setting apparatus 9 during the sewing machine stitch action, zigzag stitch in accordance with the changed maximum zigzag width is performed.
