Abstract
A presser foot 12c of a sewing machine is provided with a main body 210, a swayingly reciprocating mechanism section 230, and a thread hooking rod drive motor 240. The swayingly reciprocating mechanism section 230 has a thread hooking rod 236, and a needle thread receiving section for fixing a needle thread together with the thread hooking rod 236 is provided inside a leading-end structure section 216 of the main body 210. As a result of driving of the thread hooking rod drive motor 240, the swayingly reciprocating mechanism section 230 reciprocally moves while swaying with respect to the main body 210. When a thread take-up lever pulls up the needle thread, a circular movement arm which performs rotation movement while hooking the needle thread adjusts a rotational angle of the circular movement arm, thereby enabling adjustment of a length of a needle thread in one preceding stitch.
