Abstract

L'invention concerne un matériau de revêtement permettant de supprimer l'apparition d'un son de frottement entre des nervures et d'empêcher une pluralité de nervures d'entraver facilement la déviation des autres nervures et fournissant une texture agréable. Un matériau de revêtement (10) devant être fixé sur un matériau de base (3) comprend : un corps principal de revêtement (11) qui recouvre la surface interne (3a) du matériau de base (3) ; une pluralité de nervures (20) qui sont formées d'une seule pièce avec le corps principal de revêtement (11) de manière à faire saillie depuis le corps principal de revêtement (11) en direction du matériau de base (3) et qui sont déviées et déformées sous une charge de pression depuis la surface interne (11a) du corps principal de revêtement (11) vers le matériau de base (3) ; et un moyen de restriction (30) qui est disposé dans chacune des nervures (20) et qui restreint la direction de déviation de la nervure (20). La pluralité de nervures (20) est agencée de manière à présenter une forme polygonale continue. Le moyen de restriction (30) est conçu pour restreindre la direction de déviation de chacune des nervures (20) de sorte que les nervures (20) dévient dans les directions dans lesquelles les nervures s'éloignent les unes des autres.
