Each ditch 62 with a thin- walled bottom part 62A is formed on a top surface 46C side of the airbag door base material 46 and comes close to a mounting part 46A. An opening side end 64A of a thick-walled part 64 formed between adjacent two ditches 62 is triangle-shaped sharpening toward a back side of the vehicle in a plane view.
