Abstract
(EN)

PROBLEM TO BE SOLVED: To obtain a decorative body capable of improving the visibility of tires.

SOLUTION: A decorative body 14 includes a plurality of reflection pieces 16 including a bottom surface and a plurality of inclined surfaces that are inclined in directions other than a surface vertical to the bottom surface while setting a surface of a tire side part as the bottom surface. The inclined angle with respect to the bottom surface of the inclined surface having the minimum inclined angle with respect to the bottom surface among the reflection pieces 16 is set in a range of 5 to 60 degrees. When it is defined that a direction toward a side of a lowest part from a side of a highest part of the inclined surface having the minimum inclined angle is a vector of the inclined surface (an arrow), the decorative body 14 includes three or more kinds of reflection pieces 16 whose directions of vectors are different from one another when viewing the tire side part from the plan.

【課題】タイヤの視認性を向上させる装飾体を得る。
【解決手段】装飾体14は、タイヤサイド部の表面を底面として、底面、及び底面に垂直な面以外の方向に傾斜する複数の傾斜面を備えた複数の反射ピース16を含んで構成されている。反射ピース16の内で底面に対する傾斜角度が最も小さい傾斜面の底面に対する傾斜角度は、5〜60度の範囲内に設定されている。傾斜角度が最も小さい傾斜面の最高部位側から最低部位側に向かう方向を傾斜面のベクトル(矢印)と定義したときに、装飾体14は、タイヤサイド部を平面視したときのベクトルの向きが異なる3種類以上の反射ピース16を含んで構成されている。
