Abstract
A decorative body includes a first set through a fourth set that are a first solid shape pair at which initial points of respective vectors of a pair of reflecting pieces that are adjacent to one another are adjacent to one another and the respective vectors face in opposite directions, a second solid shape pair at which terminal points of a pair of respective vector of reflecting pieces that are adjacent to one another are adjacent to one another and the respective vectors face in opposite directions, a first solid shape group that is an aggregate in which three or more reflecting pieces at which the orientations of the vectors face in a same direction are continuous, and a third solid shape pair that is a pair formed from two reflecting pieces that do not belong to any of these.

A decorative body that includes a plurality of solid shapes, in which each solid shape has a bottom surface and an inclined surface that is inclined in a direction other than a plane that is orthogonal to the bottom surface, each of the bottom surfaces being a surface of a tire side portion,
- wherein, given that
- a direction heading from a highest region side toward a lowest region side of one of the inclined surfaces, having an angle of inclination with respect to the bottom surface which is smallest of the solid shapes, is defined as a vector of the inclined surfaces, and the highest region side of the vector is defined as an initial point of the vector, and the lowest region side of the vector is defined as a terminal point,
- a pair of the plurality of solid shapes that are adjacent to one another and at which the initial point of the vector of one solid shape of the pair of solid shapes and the initial point of the vector of another solid shape of the pair of solid shapes are adjacent to one another, and an orientation of the vector of the one solid shape and an orientation of the vector of the other solid shape, when the surface of the tire side portion is seen in plan view, face in directions opposite one another, is defined as a first solid shape pair,
- a pair of the solid shapes that are adjacent to one another and at which the terminal point of the vector of one of the solid shapes and the terminal point of the vector of another of the solid shapes are adjacent to one another, and an orientation of the vector of the one solid shape and an orientation of the vector of the another solid shape, when the surface of the tire side portion is seen in plan view, face in directions opposite one another, is defined as a second solid shape pair,
- an aggregate of the solid shapes at which three or more of the solid shapes, at which the orientations of the vectors when the surface of the tire side portion is seen in plan view face in the same direction, and at which the orientations of the respective vectors when the solid shapes are seen in a side view face in the same direction, are continuous, is defined as a first solid shape group, a pair formed from two of the solid shapes that do not belong to any of the first solid shape pair, the second solid shape pair and the first solid shape group, is defined as a third solid shape pair, the decorative body includes all of the first solid shape pair, the second solid shape pair, the first solid shape group, and the third solid shape pair, when the surface of the tire side portion is seen in plan view, all conditions including a first condition that satisfies a total surface area of the third solid shape pair>a total surface area of the first solid shape pair, a second condition that satisfies the total surface area of the third solid shape pair>a total surface area of the second solid shape pair, and a third condition that satisfies the total surface area of the third solid shape pair>a total surface area of the first solid shape group, are present.
