Abstract
A presser footof a sewing machine is provided with a main body, a swayingly reciprocating mechanism section, and a thread hooking rod drive motor. The swayingly reciprocating mechanism sectionhas a thread hooking rod, and a needle thread receiving section for fixing a needle thread together with the thread hooking rodis provided inside a leading-end structure sectionof the main body. As a result of driving of the thread hooking rod drive motor, the swayingly reciprocating mechanism sectionreciprocally moves while swaying with respect to the main body. 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.
