<p>Provided are a vehicle interior panel and an airbag device wherein it is possible to prevent the weld strength and the rigidity of a panel from deteriorating. In a vehicle interior panel, a joint surface of a flap portion has first welding ribs, second welding ribs, and a third welding rib formed thereon. The first welding ribs include the first communication grooves each allowing adjacent grids and to communicate with each other. The second welding ribs include second communication grooves each allowing adjacent grids to communicate with each other. The third welding rib includes third communication grooves formed on sides substantially perpendicular to a hinge portion. The second communication grooves are formed so as not to be successively aligned in a direction perpendicular to the second welding ribs. The first to third communication grooves form an exhaust channel allowing the air in the grids to be discharged outside during vibration welding.</p> |
