PROBLEM TO BE SOLVED: To favorably form an air bag grid part with a tear line having an elastically deformable skin material. SOLUTION: When the elastically deformable skin material 10 is set in a mold space 9 of a mold 8, and when a core resin 12 is thereafter injection-filled in a reverse face side of the skin material 10 to mold the air bag grid part 2, a partially thin machining part 21 is formed in the air bag grip part 2 using a notch machining jig 22 inserted extractably into the space 9. |
