Abstract
An overlock sewing machine includes an operating shaft that is slidable between first and second positions, and configured such that interlock switching and position switching mechanisms are operated when it is turned. The interlock switching mechanism includes a rotor that is rotatable together with the operating shaft as a single unit, an interlock switching member, and a first engagement target portion formed in the rotor. In the interlock state, setting the operating shaft to the first position engages an engagement portion of the interlock switching member with the first engagement target portion, which restricts operating shaft rotation. Sliding the operating shaft to the second position releases the engagement state between the engagement and first engagement target portions, enabling rotation of the operating shaft.
