1. A vehicle interior panel that is configured to be cleaved by an inflation pressure of an airbag, the panel comprising:
a base having a surface and a back; a covering bonded to the surface of the base, a cleavage groove formed on the back of the base, wherein, when the base is cleaved by inflation pressure of the airbag, the cleavage groove serves as a starting point of the cleavage, wherein the covering includes a ground fabric layer bonded to the surface of the base and a covering layer bonded to a surface of the ground fabric layer, the ground fabric layer being formed of the original fabric, in which the tensile strength of the original fabric in directions along its surface is anisotropic, and the tensile strength is set to be the smallest in a first direction along the surface of the original fabric and is set to be the greatest in a second direction, which is perpendicular to the first direction, wherein the cleavage groove includes a first groove section that is first cleaved when the cleavage groove is cleaved, and the covering is bonded to the base such that the first direction of the smallest tensile strength of the ground fabric layer of the covering matches with a direction perpendicular to a direction in which the first groove section extends, and wherein there is no cleavage groove formed on the ground fabric layer. |
