Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a decorative body capable of improving visibility of a tire.

SOLUTION: A decorative body 14 comprises: a first three-dimensional shape pair in which start points of vectors of a pair of reflection pieces 16 being adjacent each other are adjacent, and vectors are directed in opposite directions; a second three-dimensional shape pair in which end points of a pair of reflection pieces 16 being adjacent each other are adjacent, and vectors are directed in opposite directions; a first three-dimensional shape group being a cluster in which three or more reflection pieces 16 whose vectors are directed in the same direction are continuous; and a first set 18A to a fourth set 18D being third three-dimensional shape pairs formed of two reflection pieces 16 not belonging to any of the pairs and group, all conditions of a first condition satisfying a total area of the third three-dimensional shape pairs>a total area of the first three-dimensional shape pair, a second condition satisfying the total area of the third three-dimensional shape pairs>a total area of the second three-dimensional shape pair, and a third condition satisfying a total area of the third three-dimensional shape pairs>a total area number of the first three-dimensional shape group, are satisfied.

【課題】タイヤの視認性を向上可能な装飾体を得る。
【解決手段】装飾体14は、互いに隣接する一対の反射ピース16の各々のベクトルの始点が互いに隣接し、かつ各々のベクトルが反対方向を向いた第1立体形状対と、互いに隣接する一対の反射ピース16の終点が互いに隣接し、かつ各々のベクトルが反対方向を向いた第2立体形状対と、ベクトルの向きが同一方向を向いた反射ピース16が3以上連続した集合体である第1立体形状群と、これらの何れにも属さない2つの反射ピース16からなる対を第3立体形状対である第1セット18A〜第4セット18Dとを含み、タイヤサイド部を平面視したときに、第3立体形状対の総面積>第1立体形状対の総面積、を満足する第1条件、第3立体形状対の総面積>第2立体形状対の総面積、を満足する第2条件、及び第3立体形状対の総面積>第1立体形状群の総面積数を満足する第3条件、の全て条件が満足されている。
