  • Patent number: 8710393
    Abstract: By respectively abutting first and second outer diameter sections of a second metallic member against first and second inner diameter sections of a first metallic member, and energizing the first metallic member and the second metallic member using a pair of electrodes while pressurizing both metallic members in an axial direction thereof, a first junction where the first inner diameter section and the first outer diameter section are bonded and a second junction where the second inner diameter section and the second outer diameter section are bonded are formed between both metallic members, and a gap in which the metals do not come into contact with each other is formed between both junctions over a predetermined axial length. Accordingly, a high joint strength can be secured using less energy for bonding.
