Abstract
An integrally molded air-bag cover article is disclosed which contains an air-bag cover section which is made of a resin and has a periphery, and a frame section which is made of a resin and is integrally and continuously formed with the periphery by way of a weak section. The weak section is constituted by a resin junction in which an interface of the resin constituting the air-bag cover section and an interface of the resin constituting the frame section are joined together by bonding action between the resins. A continuous groove and a continuous protrusion are respectively formed on a front surface and a rear surface of the integrally molded air-bag cover article. The weak section is formed so as to extend from an inner face of the groove to an outer face of the protrusion.
