The present invention provides a sewing machine that not only prevents a spreader from interfering with a sewing operation so as to ensure smooth sewing, but also provides high safety, a good appearance, and ease of use. The sewing machine includes: a presser foot 1 which holds down a fabric on a throat plate 18; a presser holder 8 which supports the presser foot 1; a rotatable spreader 3 having a thread hole 14 through which sewing thread vertically passes; a spreader drive mechanism 4 which drives the rotation of the spreader 3; a reciprocating motion conversion mechanism 5 which converts the rotation of an upper shaft 7 into a linear reciprocating motion; and a link mechanism 6 which transmits the reciprocating motion produced by the reciprocating motion conversion mechanism 5 to the spreader drive mechanism 4. The spreader 3 and the spreader drive mechanism are both provided on the presser foot. The link 6 mechanism is provided on the presser holder 8.
