PROBLEM TO BE SOLVED: To prevent an air bag door hinge from damaging when it is inflated in case the air bag door and a body of a vehicular interior member are made of an identical resin. SOLUTION: A tear part 24 is formed about in the center in the longitudinal direction and on both ends in the right and left of an air bag door 20 of the instrument panel 10. A first hinge 25 is formed on respective tear parts 24 of a front door 20A and a rear door 20B and a second hinge 26 on the air bag door mounting side. The thickness of the region formed with a groove 25A of the first hinge 25 is thinner than the the region formed with a groove 26A of the second hinge 26 so the second hinge 26 starts to bend following the first hinge 25 when the air bag body is inflated. |
