PROBLEM TO BE SOLVED: To allow an air bag door formed integrally with a substrate to appropriately separate and open from the substrate in applying a pressing force of the air bag. SOLUTION: An abutting part 30 having a tip face to the proximity of a splitting expected line 16 formed along the outer edge of the air bag door 15 is disposed at a desired position of a hinge part 23 disposed in an insert member 20. The back surface of the air bag door 15 is provided with an abutting receiving part 31 that extends to be adjacent to the splitting expected line 16 and can receive the abutting part 30. When the air bag 26 of an air bag device 25 presses the hinge part 23, the abutting part 30 abuts on the abutting receiving part 31 to press the back surface edge part of the air bag door 15, thereby appropriately breaking the splitting expected line 16. |
