CLOGGING CAP AND CLOGGING STRUCTURE AND CLOGGING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a clogging cap capable of simply and sufficiently clogging an aperture formed on a structure consisting of a thermoplastic resin molded body or the like by using a general purpose rotary tool or the like without using a special machine, and a clogging structure and a clogging method using the same.SOLUTION: By a rotation friction pressure welding for pushing to inside of an injection hole 3 while rolling a shaft body 4 with status where a tip side shaft part 5 of the shaft body 4 is injected into the injection hole 3 and a melting margin part 9 is contacted with circumference of the injection hole 3, the melting margin part 9 is molten by friction heat with the circumference of the injection hole 3 and a collar part 11 contacts with an inner member 2 when the shaft body 4 is pushed with a predetermined distance equal to a gap S1 to the injection hole 3.SELECTED DRAWING: Figure 2
