COUPLING STRUCTURE OF INTERIOR TRIM PANEL FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a coupling structure of interior trim panels for a vehicle which creates no discordant noise at a coupling part of the panels when coupling a plurality of interior trim panels for a vehicle formed of extrusion-molded materials. SOLUTION: In the coupling structure 30 of the interior trim panels for the vehicle, a plurality of panels 12 and 13 formed of extrusion-molded materials of aluminum alloys abut on each other, and a sound-insulating sheet 34 is sandwiched between coupling parts including a recessed part 21 and a tip piece 27 both located at the end part in the direction orthogonal to the longitudinal direction of the panels 12 and 13. Further, the coupling parts of the abutting panels 12 and 13 are fixed with each other with a rivet 36 (a fastening tool) passing through the sound-insulating sheet 34, and a porous sound absorbing material 32 is interposed along the longitudinal direction between the coupling parts.
