強固に接合させることができる。2. Description of the Related Art For example, when resin parts are joined to each other, as shown in FIG. 6, a welding boss 2 is formed projectingly on one resin part 1 and a resin part 3 on the other side is formed.
An insertion hole 4 into which the welding boss 2 is inserted is opened. After the welding boss 2 is inserted into the insertion hole 4, the distal end of the welding boss 2 is ultrasonically welded by an ultrasonic welding horn 5. 7, the resin parts 1 and 3 can be firmly joined by caulking the tip of the welding boss 2 as shown in FIG.

されている。As described above, when the resin parts 1 and 3 are joined by caulking the welding boss 2 having a hollow structure, for example, as shown in FIG. Is decorated with the skin material 6, a gap corresponding to the thickness of the skin material 6 is formed between the resin parts 1 and 3. If caulking is performed by the ultrasonic welding horn 5, FIG. As shown in the figure, it has been pointed out that the base of the welding boss 2 melts and enters into the gap, resulting in a decrease in crimping allowance and a predetermined welding strength cannot be obtained.

In particular, it is an object of the present invention to provide a crimping structure for a resin component capable of obtaining a strong bonding strength.

【０００６】[0006]

る。According to the present invention, a welding boss is formed on one side of resin parts joined and fixed to each other, and the welding boss is formed on the other side. The welding boss is inserted into the insertion hole, and then, after the welding boss is inserted into the insertion hole, the tip of the welding boss is welded.
With a hollow structure, or a small diameter welded part and a solid base ,
Alternatively , it is characterized in that it is set as a large diameter non-welded portion.

度が強化される。As is apparent from the above configuration, since the base of the welding boss is set as a non-welded portion, even if a slight clearance is set between the resin parts, the molten resin of the welding boss is not covered by the gap. As a result, a large crimping margin is formed, and the welding strength of the welding boss is enhanced.
