A draw texturing machine comprising: five-axial false-twisting devices aligned in a base longitudinal direction, each of which being able to apply twisting to two yarns at the same time by circular plate members, the circular plate members being provided at five rotational shafts, the five rotational shafts extending in an axial direction orthogonal to the base longitudinal direction, and a working space being formed along the base longitudinal direction for yarn threading performed by the five-axial false-twisting devices, and each of the five-axial false-twisting devices including: a first false-twisting unit which includes, among the five rotational shafts, two first independent rotational shafts (72, 73) and a common rotational shaft which virtually form apexes of a first triangle when viewed in the axial direction, the first false-twisting unit applying the twisting to a first yarn running inside of the first triangle; and a second-false twisting unit which includes, among the five-rotational shafts, two second independent rotational shafts (74, 75) and the common rotational shaft which virtually form apexes of a second triangle when viewed in the axial direction, the second false-twisting unit applying the twisting to a second yarn running inside of the second triangle, the two first independent rotational shafts (72, 73) opposing the two second independent rotational shafts (74, 75) over the common rotational shaft in the base longitudinal direction, the first false-twisting unit being configured such that the first yarn is threaded to the first false-twisting unit by being introduced from a gap between the two first independent rotational shafts (72, 73) into the inside of the first triangle, the second false-twisting unit being configured such that the second yarn is threaded to the second false-twisting unit by being introduced from a gap between the two second independent rotational shafts (74, 75) into the inside of the second triangle, one of the two first independent rotational shafts (72, 73) being a first movable shaft placed on a near side which is closer to the working space than the other of the two first independent rotational shafts (72, 73), the one of the two first independent rotational shafts (72, 73) being movable between a first operating position in which each of the five-axial false-twisting devices is in operation and a first yarn threading position which is on the near side of the first operating position, and one of the two second independent rotational shafts (74, 75) being a second movable shaft placed on the near side of the other of the two second independent rotational shafts (74, 75), the one of the two second independent rotational shafts (74, 75) being movable between a second operating position in which each of the five-axial false-twisting devices is in operation and a second yarn threading position which is on the near side of the second operating position; characterised in that the first movable shaft and the second movable shaft are swingable with the common rotational shaft as a swing shaft center. a first false-twisting unit which includes, among the five rotational shafts, two first independent rotational shafts (72, 73) and a common rotational shaft which virtually form apexes of a first triangle when viewed in the axial direction, the first false-twisting unit applying the twisting to a first yarn running inside of the first triangle;
