(54) HOLLOW GUIDE SHAFT, AIR-JET SPINNING DEVICE, AND TEXTILE MACHINERY


(57) A hollow guide shaft (38) includes a first member (40) and a second member (50). In the first member (40) are formed an introducing opening (42) through which a fiber bundle (8) is introduced, a first fiber passageway (47) through which the guided fiber bundle (8) passes, and an assisting nozzle (45) arranged so as to generate inside the first fiber passageway (47) a swirling air current that conveys the fiber bundle (8) downstream during yarn discharge spinning. In the second member (50) is formed a second fiber passageway (53) through which the fiber bundle (8) that has passed through the first fiber passageway (47) passes. The second member (50) is arranged as a separate member from the first member (40).
