　振動制御部２１は、ホーン部２３により第１接合部材１１に対して音波振動及び／又は超音波振動を与える（ステップＳＴ２）。音波振動及び／又は超音波振動は、縦振動（加圧する方向と同じ方向の振動）である。音波振動は２０ｋＨｚ以下であり、超音波振動は２０ｋＨｚよりも高いものである。 The vibration control unit 21 applies sonic vibration and / or ultrasonic vibration to the first joining member 11 by the horn unit 23 (step ST2). Sonic vibration and / or ultrasonic vibration are longitudinal vibrations (vibrations in the same direction as the direction of pressurization). The sonic vibration is 20 kHz or less, and the ultrasonic vibration is higher than 20 kHz.
　第１接合部材１１は、音波振動及び／又は超音波振動を与えられると共振伸縮する。第１接合部材１１が共振伸縮することにより、干渉部１３1及び１３2は、突出部１８1及び１８2を超えて凹部１７1及び１７2に嵌まる。これにより、第１接合部材１１と第２接合部材１５の機械的な接合が実現できる。このとき、瞬時の溶解や拡散接合を行うことができる。いわば、３次元固定と同時に封止をすることができる（ＳＦＢ：Sound Fit Bonding）。これは、金属などの焼き嵌に代わるものである。 The first joining member 11 resonates and expands and contracts when subjected to sonic vibration and / or ultrasonic vibration. By first bonding member 11 resonates stretch, the interference portions 13 1 and 13 2, the protruding portions 18 1 and 18 2 Beyond recesses 17 1 and 17 2 to the fit. As a result, mechanical joining of the first joining member 11 and the second joining member 15 can be realized. At this time, instantaneous melting and diffusion bonding can be performed. So to speak, it can be sealed at the same time as three-dimensional fixing (SFB: Sound Fit Bonding). This is an alternative to shrink fitting of metals and the like.
　振動制御部２１は、発振を終了するか否かを判定する（ステップＳＴ３）。振動制御部２１は、発振を終了しないとするならば、発振を継続する。発振を終了するとするならば、発振を停止して、圧力調整部７は加圧を停止する（ステップＳＴ４）。 The vibration control unit 21 determines whether or not to end the oscillation (step ST3). If the vibration control unit 21 does not end the oscillation, the vibration control unit 21 continues the oscillation. If the oscillation is to be terminated, the oscillation is stopped and the pressure adjusting unit 7 stops the pressurization (step ST4).
　振動制御部２１は、嵌装により発振を停止してもよく、嵌装による機械的な接合状態を利用して継続して発振してさらに溶解や拡散接合を行ってもよい。ジョイント設計（干渉部１３及び凹部１７の形状設計など）や接合条件（与える振動の条件など）で、３次元固定（ＳＦ（Sound Fit）音嵌め）からＳＦＢ接合まで、自由に制御することができる。 The vibration control unit 21 may stop oscillating by fitting, or may continuously oscillate using the mechanical joining state by fitting to further perform melting or diffusion joining. It is possible to freely control from 3D fixing (SF (Sound Fit) sound fitting) to SFB joining by joint design (shape design of interference part 13 and recess 17 etc.) and joining conditions (conditions of applied vibration etc.). ..
