Document Type and Number:
WIPO Patent Application WO/2018/173865
Kind Code:
Provided is an overlock sewing machine that prevents switching to an interlocked state or to an interlock release state against the will of a user and that prevents the position of an upper knife from being switched to an interlocked position or to a retracted position. The overlock sewing machine is provided with an operating shaft that is configured so as to be slidable between a first position and a second position and that operates an interlock switching mechanism and a position switching mechanism by rotating. The interlock switching mechanism comprises: a rotating body provided so as to be capable of rotating together with the operating shaft; an interlock switching member; and a first engaged section formed on the rotating body. When the operating shaft is arranged in the first position while in an interlocked state, an engagement section of the interlock switching member is engaged with the first engaged section and rotation of the operating shaft is restricted, and sliding the operating shaft to the second position releases the engaged state of the engagement section and the first engaged section, thereby allowing rotation of the operating shaft.
