CONSTITUTION: A traverser guide device comprises a bobbin(10), a movable block(20) and a cover(30). The bobbin comprises a plurality of spiral grooves(11) and a through hole(12). A wire(1) is wound on the spiral grooves. A shaft is inserted into the through hole of the inner central part of the bobbin. The movable block comprises an insertion hole(21) and a coupling protrusion. The wire passes through the insertion hole of the movable block and is coupled to the spiral groove. The coupling protrusion is coupled to the spiral groove. The cover comprises a guide slot and a separation preventing unit(32).
