Abstract: After the fixing of an angle indexing body to a holder by fixtures is canceled by loosening the fixtures, a resonator is turned by operating the angle indexing body with an axis in a vibration transmission direction as the center of rotation, a bonding work face is replaced by another bonding work face, and the angle indexing body is fixed to the holder by the fixtures so that the new bonding work face becomes parallel to the top face of a mounting table. Therefore, the replacement of the bonding work face can be simplified. Since overlapped workpieces are sandwiched between the bonding work face of the resonator and the mounting table, the mounting table makes a follow-up movement by a bearing composed of a spherical projection portion and a spherical depression portion to ensure that the bonding work face becomes parallel to the top face of the mounting table, thereby making it possible to optimize the position of the sandwiched workpieces.
