Abstract

In a molding composed of a molding body comprising a front surface, a bottom, a side portion and a hollow portion, and of an adhesive layer constituted at the bottom, the thin molding side portion extends along the front surface, and the bottom is provided with a projection which projects on one side or both sides of the bottom separate from the front surface and the molding side portion. When the front surface is pushed, the pushing force applied to the front surface produces the fulcrum of the bending moment at the molding side portion and the plane pressure from the fulcrum to the front surface in the direction towards the inside of the bottom, and at the same time the contact pressure applied to the point of action of force is distributed in the plane pressure distribution towards the front surface which attenuates from the peak value below the point of action of force to both sides gradually.
