To provide an apparatus preventing manufacturing trouble due to a bending deformation by not causing a bending deformation of different materials of long size in a joining apparatus to join by heating/rolling long size materials.
In a joint joining apparatus for long size different materials, by which members to be joined made of long size different metals are overlapped and are heated up to a prescribed temperature by passing a heating means in vacuum and then is rolled to manufacture a joined material, a non- contact type detection means 40 to detect presence or absence of bending in an direction outside the face of rolled joining materials is arranged to an outlet side of press rollers 31, further, a downward load imparting means 50 to push down the joining materials 3 bent in an direction outside the face is arranged to an outlet side upper part of the pressure roller 31 in the transfer direction as arraying in one or more.
