<p><P>PROBLEM TO BE SOLVED: To prevent variations from occurring in the welding area of a component and the base material and prevent excessive ultrasonic vibration from being applied on a board material or a cushion layer composing the base material in an ultrasonic welding method which presses an ultrasonic horn to the part made of thermoplastic synthetic resin to weld the base material. <P>SOLUTION: After a bracket part 10 made of thermoplastic synthetic resin is mounted on the surface of a base material 14, the ultrasonic horn 12 is pressed to the bracket part 10 and a part of the bracket part 10 is welded. A recessed part 20 for filling with a molten resin 22 which is generated by melting a part of the bracket part 10 is formed on the surface of the side abutting on the base material 14 of the bracket part 10. When the ultrasonic horn 12 is pressed to the bracket part 10, the ultrasonic horn 12 is pressed so that the recessed part 20 exists on the axis line L of the ultrasonic horn 12. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
