Provided is a threader for an overlock machine that allows the whole machine to be made compact and allows an operator to carry out threading 5 reliably with one hand. The threader comprises: a threading shaft that moves vertically and is supported rotatably, with a shaft core being taken as a central axis; a threading hook that is fixed to the lower end of the threading shaft and that includes a hook part that can be inserted into the needle eye of a sewing needle and a first guide part that guides the hook 10 part to the needle eye; and a thread guide member that guides a needle thread to the hook part in the vicinity of the descent limit point of the threading shaft. The threading hook is rotated by a predetermined angle so that the hook part is inserted into the needle eye of the sewing needle in the vicinity of the descent limit point of the threading shaft. The threading 15 hook and the thread guide member are rotated in opposite directions to each other and thereby the thread guide member is rotated by the predetermined angle so that the thread hooking part intersects the sewing needle beyond the position of the sewing needle in the vicinity of the descent limit point of the threading shaft. The threading shaft moves according to the relative 20 positional relationship between the needle eyes of a plurality of sewing needles. |
