<P>PROBLEM TO BE SOLVED: To solve a problem of impairing flatness as a whole because only a paving stone of large load sinks and a luminaire or the like of small load projects from the paving stone when arranging components of the luminaire or the like adjacently to the paving stone. <P>SOLUTION: A paving stone body 0100 is provided with through-holes 0101 formed in stepped shape. The components disposed in the through-holes are thereby locked by the stepped shape, and even if the paving stone body sinks, it sinks while maintaining the initial state of a position relationship between the paving stone body and components. Consequently, if flatness is kept in the initial state, the flatness is not impaired by the subsequent projection of the components or the like. <P>COPYRIGHT: (C)2008,JPO&INPIT |
