ABSTRACT OF THE DISCLOSURE An upper thread (6) is guided to extend vertically by a pair of thread guides (4) vertically opposed to each other. A thread take-up lever (9, 9a, 9b, 9c, 46) is installed so that it is horizontally reciprocated across the space between the pair of thread guides. When the thread take-up lever is reciprocated, it engages the thread positioned between the thread guides to draw it in V-form during its forward travel and stops drawing the thread to form a slack in the thread in its return travel. To prevent this slacked thread portion from clinging to the thread take-up lever, a thread holding member (28, 29, 30, 31, 32, 33) or thread braking member (36, 37, 38, 41, 45, 49) made of easily deformable material and adapted to contact the thread to thereby prevent the thread from following the movement of the thread is installed at at least one position along the path of travel of the thread engaging portion (10, 10a, 10b, 10c, 50) of the thread take-up lever.
