PROBLEM TO BE SOLVED: To provide a vehicle interior material which enables secure joint of three or more resin components and weight reduction.SOLUTION: In a vehicle interior material 1, a first component 10, a second component 14, and an intermediate part 12 disposed between the first component 10 and the second component 14, which are made of thermoplastic resin, are joined by welding. The first component 10 has a rib 10c protruding to the second component 14 side. The intermediate component 12 has: a through hole 12c through which the rib 10c is inserted; and a wall part 12b provided around the through hole 12c and protruding to the second component 14 side. The second component 14 has a through hole 14b into which the rib 10c and the wall part 12b are inserted. The rib 10c, the wall part 12b, and the second component 14 are welded.SELECTED DRAWING: Figure 1
【課題】3以上の樹脂部品の強固な接合が可能で、さらに軽量化が可能な車両用内装材を提供する。【解決手段】車両用内装材1は、それぞれ熱可塑性樹脂製の第1部品10、第2部品14、及び第1部品10と第2部品14の間に配置される中間部品12が溶着により接合され構成される。第1部品10は、第2部品14側に突出したリブ10cを有する。中間部品12は、リブ10cが挿通される貫通孔12cと、貫通孔12cの周囲に設けられ、第2部品14側に突出した壁部12bと、を有する。第2部品14は、リブ10cと壁部12bとが共に挿通される貫通孔14bを有する。リブ10cと、壁部12bと、第2部品14が溶着される。【選択図】図1
