PROPELLER SHAFT MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a propeller shaft capable of reducing costs for surface treatment applied to reduce stick slip.SOLUTION: A propeller shaft comprises: a first shaft 10 having a yoke on one end; a second shaft 20 slidably coupled with the other end of the first shaft 10; and a surface treatment member 30 arranged at a coupling portion of the first shaft 10 and the second shaft 20, and subjected to surface treatment for improving slidability of the second shaft 20 to the first shaft 10. The surface treatment member 30 is formed by applying the surface treatment to a base material separate from the first shaft 10 and the second shaft 20, and is arranged at the coupling portion of the first shaft 10 and the second shaft 20 after the surface treatment.
