Holding structure of an ultrasonic vibration transmission mechanism

A holding structure of an ultrasonic vibration mechanism, comprising:

• a horn body formed as a solid body having a length that is nearly a length of half a wavelength of an applied ultrasonic wave applied to the horn body by an ultrasonic vibration welding device in which the holding structure is disposed;
• the horn body having a first position Pb that is at an input end at which the applied ultrasonic wave is applied to the horn body and a second position Pa spaced a prescribed distance from the first position Pb that is ¼ a wavelength of the applied ultrasonic wave;
• at least one holder disposed on a side of the horn body with thin sheet connectors associated with that holder extending between that holder and the horn body to maintain a space between the horn body and that holder, the thin sheet connectors including a flat thin sheet connector extending between the horn body from the first position Pb of the horn body to that holder, and a S-shaped thin sheet connector extending between the horn body from the second position Pa to that holder;
• the horn body, each holder and associated thin sheet connectors constructed in one piece;
• and
• each holder holders affixable to an associated holding element of the ultrasonic vibration welding device.
