ABSTRACT OF THE DISCLOSURE A roof lining structure in a motor vehicle includes a roof lining base member and a vibration-damping layer interposed between an upper surface of the base member and a lower surface of a roof panel of the motor vehicle. The roof lining base member comprises a support layer having a cellular structure, and a reinforcing layer disposed at least partly in the roof lining base member. The upper sur- face of the vibration-damping layer is held in intimate con- tact with the lower surface of the roof panel. The vibration-damping layer is bonded to the roof panel by an adhesive layer. The vibration-damping layer is made of a material having such a mechanical strength that the vibration-damping layer will be torn apart vertically with a tearing force weaker than the bonding strength of the adhe- sive layer.
