The length of each side of the soft polyvinyl chloride sheet 122 is longer than the length of each corresponding side of the surface member 102, and the soft polyvinyl chloride sheet 122 has flexibility and a heat melting property. The soft polyvinyl chloride sheet 122 is bonded at a prescribed distance with all the sides of the surface member 102. At least one side of the surface member 102 is exposed.
