摘要： PROBLEM TO BE SOLVED: To prevent occurrence of a defective phenomenon in which an aperture between an inner pipe and an outer pipe at a bend portion becomes wider in the inner periphery side of the bend while it becomes narrower in the outer periphery side. SOLUTION: In the manufacturing method of the double walled pipe member, a hydraulic bulging machine is employed, which has a metal die set comprised of a first die 11 that has the bend portion and an inner surface at least partially contacted with an outer periphery side of the bend of the outer pipe 2a at the bend portion of the double walled pipe workpiece 2 structured by the inner pipe 2b and the outer pipe 2a, and a second die 12 to form the double walled pipe workpiece 2 into the desired profile. After the double walled pipe workpiece 2 is set in the first die 11, a fluid is introduced into the inner pipe 2b and the aperture between the inner pipe 2b and the outer pipe 2a, while in the bend portion the inner pipe 2b is fixed via the outer pipe 2a by the first die 11 and restrained from shifting toward the outer periphery side of the bend of the inner pipe 2b at least during a first process. Then, in the second die 12, the outer pipe 2a of the double walled pipe workpiece 2 is bulged inside the second die 12 and formed into a product profile. The aperture between the inner pipe and the outer pipe becomes uniform not only in the straight portion but also in the bend portion. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a vehicle propeller shaft capable of increasing lower limit strength without increasing the thickness of a steel plate constituting a welded pipe and the thickness of a yoke.
SOLUTION: In a jointing part 76 between the yoke 56 and the electric resistance welded pipe 58, a mating portion 62 of the electric resistance welded pipe 58 is positioned within a region SS where tensile stress between the yoke 56 and the electric resistance welded pipe 58 periodically changed in synchronization with rotation of a hook joint 30 is particularly relatively lowered. Thus, this prevents the mating portion 62 of the electric resistance welded pipe 58 from being positioned in a phase region where tensile stress is increased during one rotation of the yoke 56. As a result, without increasing the thickness of the steel plate constituting the electric resistance welded pipe 58 and the thickness of the yoke 56, the lower limit strength in the jointing between the yoke 56 and the electric resistance welded pipe 58 can be increased.
