摘要 PROBLEM TO BE SOLVED: To provide an airbag cover body, wherein it is difficult for any appear ance failures such as uneven luster or the like caused by injection molding to occur in the vicinity of a first tearing line. SOLUTION: A single-layer airbag cover body is made of a thermoplastic elastomer material by injection molding. A tearing line formed in a cover main body part 14 includes a first tearing line extended straight by crossing a material flowing direction during the injection molding, and a second tearing line in parallel with the material flowing direction. The first tearing line is made of a first breaking groove 36 formed in the backside. The upstream side slope angle β of the first breaking groove 36 with respect to the material flowing surface is set larger than a downstream side slope surface y.
