PROBLEM TO BE SOLVED: To inhibit a thread from being exposed in a side part of a junction.SOLUTION: A tire reinforcement material 10 is constituted of a ply 18 in which a plurality of cords 14 arranged in parallel with each other is coated with a topping rubber 16 and has a junction 12 where ends of plies 16 overlap and are joined. Topping rubber thicknesses T1, T2 of plies 18 in side parts 24, 26 of the junction 12 are larger than topping rubber thicknesses T3, T4 of plies 18 in the junction 12.SELECTED DRAWING: Figure 1
【課題】接合部の脇部における糸見えを抑える。【解決手段】実施形態に係るタイヤ補強材10は、平行に配列された複数本のコード14をトッピングゴム16で被覆してなるプライ18からなるタイヤ補強材であって、プライ16の端部同士を重ね合わせて接合した接合部12を有する。接合部12の脇部24,26におけるプライ18のトッピングゴム厚みT1,T2が、接合部12におけるプライ18のトッピングゴム厚みT3,T4よりも大きい。【選択図】図1
