摘要： A thread holding mechanism for sewing machines is disclosed holding a thread when the thread is passed through an eye of a sewing needle. The mechanism includes a thread holding member including a thread holding portion capable of holding the thread, an operating force transmitting member to which an external force is applied, a moving member to which the operating force transmitting member transmits the force, moving the thread holding member near the eye of the needle, and a thread nipping member provided in the thread holding member for releasably nipping the thread, a switching member provided near a movement path of the thread holding member for switching the thread nipping member to an interposition releasing side temporarily prior to thread holding in synchronization with a predetermined stage of a step of moving the thread holding member.
