Abstract
An instrument panel of an automobile includes a base and a covering bonded to a surface of the base. A cleavage groove is formed on the back of the base. When the base is cleaved by inflation pressure of an airbag, the cleavage groove serves as a starting point of the cleavage. The covering is formed by a ground fabric layer made of knitted fabric and a covering layer bonded the surface of the ground fabric layer. The ground fabric layer is formed of an original fabric in which the tensile strength in directions along its surface is anisotropic. The cleavage groove includes a first groove section, which is cleaved first. The covering is oriented with respect to the base such that the direction of the smallest tensile strength of the ground fabric layer matches with a direction perpendicular to the direction in which the first groove section extends.
