製造工程が極めて複雑化する等の問題点があった。In addition, in the case where the door trim base material 30 and the retainer bracket 31 are bonded by ultra-8 wave welding means (i.e., by applying ultrasonic vibration to the tool horn 36 from the surface side 30a of the door trim base material 30, the joint surface is softened and melted, Since the welding is carried out under pressure, for example, if the fiber M density of the welded part of the door trim base material 30 is low, the molten resin will seep out to the surface side 30a, creating a welded part on the smooth surface 30a, and damaging the skin material. When pasted, there is a problem that the welded part stands out, and if the fiber density of the welded part is high, a scorching phenomenon occurs in the welded part, and this scorch mark also comes out on the surface of the skin material. For this reason, as shown in FIG.
In this case, the retainer bracket 43 was brought into contact with the 11th surface 42 side and welded by applying ultrasonic vibration to both sides of the mounting board 44 using the tool horn 45. In this case, the fiber density of the welded part of the trim base material 41 was If it is too low, seepage will occur on the surface 46 on the surface plate side, and the welding area will be small, so when considering installation strength, a method has been used in which welding is performed from the surface side. In addition, if there are variations in the thickness of the door trim base material 30 or if the II navy blue density is low, variations in the transmission of ultrasonic vibrations will occur, resulting in a difference in welding strength. 31 may come off, and in this way, the surface side 30a of the door trim base material 30
In ultrasonic welding, the fiber density of the door trim base material 30,
There were problems such as restrictions due to board thickness accuracy and the like, and solving this problem would require an extremely complicated manufacturing process.
