Abstract

In a sewing machine, an elevating unit is configured to be integrally raised and lowered with a threading lever of a threading apparatus. Furthermore, an operating lever is coupled to a lever interlocking mechanism that interlocks with the rotational operation of the operating lever. Upon pressing threading lever downward from an initial position when operating lever is at an operating position, an elevating unit engages with lever interlocking mechanism. Operating force applied to threading lever is transmitted to operating lever via lever interlocking mechanism, thereby turning operating lever from operating position to non-operating position. Accordingly, even when a presser is at a raised position, by pressing threading lever downward, operating lever is turnable from operating position to non-operating position, thereby allowing presser to return to pressing position.
