PROBLEM TO BE SOLVED: To prevent such trouble that the yarn quality and the productivity degrade by the scattering of a traveler due to the softening of the surface of the traveler and development of yarn break according to the rise of the surface temperature of the traveler especially in high speed spinning. SOLUTION: The traveler is formed by using an alloy steel wire, and a carburization-nitriding treatment is applied to this traveler. Thereafter, quenching and tempering are applied, a salt-bath treatment is performed, a nitride layer having HV650-HV750 Vickers hardness is formed on the base material surface, and an oxide film is formed on this surface to provide the traveler for a spinning machine.
