WIPO Patent Application WO/2018/173864
Kind Code:
Provided is an overlock sewing machine that switches satisfactorily from an interlock release state to an interlocked state. When the overlock sewing machine is in the interlocked state with an upper knife in an interlocked position, rotating an operating shaft toward one side around an axis causes an interlock switching mechanism to displace the other end of a rod and switch to the interlock release state, a pressing portion presses a first switching portion, the first switching portion causes a swinging member to swing toward a forward motion side, and the upper knife is moved to a retracted position. When in the interlock release state with the upper knife in the retracted position, rotating the operating shaft toward one side around the axis causes the pressing portion to press a second switching portion, the second switching portion causes the swinging member to swing toward a return motion side, the upper knife is moved to the interlocked position, and the interlock switching mechanism displaces the other end of the rod and switches to the interlocked state.
