A zigzag width range setting apparatussets a minimum value and a maximum value of a zigzag width of a needle. When the sewing machine is in operation, if the minimum value of the zigzag width preset by the zigzag width range setting apparatusis higher than 0, a zigzag action is performed in a minimum zigzag width at no operation of a knee lifter(an amount of operation of zero), and if the minimum value is 0, the zigzag width of the needleis 0 at zero amount of operation of the knee lifter, that is the zigzag action is not performed, and stitching is performed by moving the needlewidthwise in accordance with the amount of operation of the knee lifter. If the maximum value is changed by the zigzag width range setting apparatusduring the sewing machine stitch action, zigzag stitch in accordance with the changed maximum zigzag width is performed.
