PROBLEM TO BE SOLVED: To prevent deterioration of an external appearance quality due to thermal deformation of an air bag lid part by using a multi-layer laminate sheet. SOLUTION: This air bag device for the vehicle is so constituted that the air bag lid part 4 is formed by welding a core material 14 to the rear face of the multi-layer laminate sheet 13 having at least a skin layer 10 and a barrier layer 12 and a grooved cleavage line 15 is formed from the rear side of the air bag lid part 4. The cleavage line 15 is formed into such a depth as penetrating the core material 14 and leaving a part of the barrier layer 12. |
