Joined structures are disclosed, which comprise first and second members (1,3) having different coefficients of thermal expansion and an intermediate member (2) joining the first and second members. The intermediate member (2) has yield stress smaller than those of the first and second members, and a tapered portion (4) is formed at an outer peripheral surface of the intermediate member (2). The tapered portion (4) has a variable cross-sectional area orthogonal to an axis of the joined members, this area being larger at one end of the tapered portion near that one of the first and second members having a smaller coefficient of thermal expansion. |
