Abstract

PROBLEM TO BE SOLVED: To prevent rising and peeling off caused by a generation of an air accumulation by incorporating a bubble into an adhesive and remaining the bubble as an air-removing hole for removing an air in the air accumulation generated between an interior part body and the adhesive. SOLUTION: A bubble 24 is incorporated into an adhesive 23 when the adhesive 23 and a curing agent are stirred. Further, the adhesive 23 into which the bubble is incorporated is overlapped to a covering material 22 of a door trim body. The bubble 24 incorporated into the adhesive 23 becomes a fine hole by evaporating a solvent of the adhesive when the adhesive 23 is cured by heating, and the fine hole becomes an air-removing hole 25. Thus, since the bubble 24 incorporated into the adhesive 23 becomes the fine hole as such and a large number of air-removing holes 25 are formed on a layer of the adhesive 23, an air can escape from an air accumulation 27 caused by a crimp 22a of the covering material 22 through the air-removing holes 25. Accordingly, rising and peeling off caused by a generation of the air accumulation 27 are extinguished.
