精度の良い結合体が得られない難点があった。(b) Prior art and problems Generally, plate-like members and tubular members are joined by welding, brazing, etc., but the reliability of the joint is affected and thermal stress occurs due to temperature rise of the plate-like member. Warping and deformation occur in precisely formed plate-shaped members due to the relaxation of residual stress.
There was a problem that a highly accurate bonded body could not be obtained.

択上で多くの制約がある。It has also been proposed to join a plate member and a tubular member by means of plastic working, but conventional methods of this type require several pressure forming steps and an annealing step. In addition to being expensive, there are limits to the height and wall thickness of the tubular members to be joined. In addition, due to the characteristics required for the joining member, the properties required for the plate-like member and the tubular member may differ, and in such cases, the materials of the plate-like member and the tubular member that make up the joining member may be different from those required. Although it is desirable to use different materials that match the characteristics, there are many restrictions on material selection when joining members of different materials by brazing or welding.
