<P>PROBLEM TO BE SOLVED: To prevent the deformation of an adherend and to secure high attachment strength in an ultrasonic welding method for a resin component in which the resin component is integrated with the adherend. <P>SOLUTION: When ultrasonic machining is applied to an ultrasonic machining point 40 by an ultrasonic horn 50 with a clip fitting seat (resin component) 30 superposed on a roof trim main body (adherend) 20, a projection 33 for a welding part is formed. A space 34 for absorbing a molten resin M is formed around the projection 33, or a concave groove 37 or a recess 38 to be a passage for the molten resin M is set at the ultrasonic machining point 40, so that sufficient welding strength is secured without having an adverse effect of heat or a press pressure from the ultrasonic horn 50 on the adherend 20. <P>COPYRIGHT: (C)2007,JPO&INPIT |
