To provide a manufacturing method of intermeshing shaft which can improve working efficiency when intermeshing an intermeshing member of the intermeshing shaft and an intermeshing member of the other element.

A sun screw 12 as an intermeshing member, a front sun gear 11 and a front sun gear 13 are formed on a periphery of a basic sun shaft 10A by rolling, and a hit marking 15 for grasping a relative spinning phase and an axially relative distance with these intermeshing members is formed at a location separately from the intermeshing member on the periphery.
