A structure of the hollow torque transmission member having a bellows portion in the middle section in the axial direction is manufactured at low cost by bulge molding such as hydroforming molding. A thin thickness portion having a smaller thickness in the radial direction than other portion is provided in the middle section in the axial direction of a hollow material. A hollow torque transmission member comprising a bellows portion is obtained by expanding the thin thickness portion outward in the radial direction by performing hydroforming molding to the hollow material.
