<p>An ultrasonic vibration welding device and an ultrasonic vibration horn capable of sufficiently assuring a pass line for welding operation and preventing ultrasonic vibration from occurring in vertical component direction, the ultrasonic vibration welding device (1000) wherein the ultrasonic vibration horn (2000) is supported near a nordal point (NP) where no vibration is induced when ultrasonic vibration is generated on the ultrasonic vibration horn (2000)with the nordal point (NP) facing just above a working surface for the welding treatment; the ultrasonic vibration horn (2000) wherein a convergently tilted working surface (2110) and an opposed surface (2110X) are disposed, symmetrical with each other, on a connection operating part (2100) having a cross section symmetrical with respect to the longitudinal center axis thereof, and recessed parts (2133) continued to the working surface (2110) and the opposed surface (2110X) are formed symmetrical with each other so that only the ultrasonic vibration parallel with the connected working surface (2110) is generated on the working surface.</p> |
