Abstract

The sewing machine is configured to prevent a string-shaped material from catching on a nearby component part thereof. A guide member for guiding the string-shaped material toward a sewing position reciprocates in a lateral direction to sew the string-shaped material to a sewing workpiece through zigzag stitching. A restriction member is disposed close to the guide member and has a laterally elongated section having a length corresponding to a range of reciprocation of the guide member. The string-shaped material extending from the guide member to the sewing position is positioned to be located beneath the laterally elongated section of the restriction member. With the presence of the laterally elongated section, when the guide member reciprocates, the string-shaped material being swung left and right by the guide member is reliably positioned (restricted) beneath the laterally elongated section. The restriction member may function as a presser foot too.
