PROBLEM TO BE SOLVED: To prevent a door panel part which is opened by the pressure of an airbag from being ruptured and separated at hinge parts and scattered as it is opening. SOLUTION: A rupturing portion 38 is provided in the portion of a support frame part 28 adjacent to the hinge parts 32; if an excessive stress is applied to the hinge parts 32 during the process of opening the door panel parts 26 and 26, the rupturing portion 38 is ruptured to separate the door panel parts 26 and 26 from the support frame part 28. The door panel parts 26 and 26 separated from the support frame part 28 are supported by the outer edge wall 24 of a surface cover part 22 located on the outer edge of the support frame part 28 to prevent scattering of the door panel parts 26 and 26. The rupturing portion 38 comprises, e.g. a grooved portion 40 formed as a thin-walled portion in the support frame part 28. |
