Abstract:
An ultrasonically joining apparatus for joining a first member and a second member, said first member having a first portion where a heat generator is attached and a second portion where said heat generator is not attached, comprising:an oscillator for outputting a high frequency electric power; a vibrator for transforming said high frequency electric power into an ultrasonic vibration; a cone for converting said ultrasonic vibration; and a horn pressed against said first member for transmitting said converted ultrasonic vibration to said first member, said horn having a high friction surface formed thereon in correspondence with said second portion of said first member for contacting said first member to prevent a slide of said horn relative to said first member, and a protective surface formed thereon in correspondence with said first portion of said first member for protecting said first member, said protective surface being more harmless to said first member relative to said high friction surface.
