Title (EN) TIRE
(FR) PNEUMATIQUE
(JA) タイヤ
Abstract:
(EN) This tire is provided with: an annular tire casing; and a belt which is provided on the outer periphery of the tire casing and in which resin-coated cords formed by coating reinforcement cords with resin are bonded to the tire casing by being spirally wound on the outer periphery of the tire casing in the tire circumferential direction, and adjacent portions of the resin-coated cords in the tire axial direction are bonded to each other, wherein end sections of the resin-coated cords have a tire radial direction cross-sectional area that gradually decreases toward the end of the resin-coated cord, and the reinforcement cords are exposed on tapered surfaces.
(FR) L'invention concerne un pneu pourvu : d'un boîtier de pneu annulaire ; et d'une ceinture qui est disposée sur la périphérie externe du boîtier de pneu et dans laquelle des cordons revêtus de résine formés par revêtement de cordons de renforcement avec de la résine sont liés au boîtier de pneu en étant enroulés en spirale sur la périphérie externe du boîtier de pneu dans la direction circonférentielle du pneu et des parties adjacentes des cordons revêtus de résine dans la direction axiale du pneu sont liées les unes aux autres, les sections d'extrémité des cordons revêtus de résine ayant une aire de section transversale de direction radiale de pneu qui diminue progressivement vers l'extrémité du cordon revêtu de résine, et les cordons de renforcement étant exposés sur des surfaces effilées.
(JA) タイヤは、環状のタイヤケースと、タイヤケースの外周に設けられ、補強コードを樹脂で被覆して構成された樹脂被覆コードがタイヤケースの外周にタイヤ周方向に螺旋状に巻かれてタイヤケースに接合されると共に、樹脂被覆コードにおけるタイヤ軸方向に互いに隣接する部分同士が接合されたベルトと、を備え、樹脂被覆コードの端部は、タイヤ径方向断面の面積が樹脂被覆コードの末端に向かって漸減すると共に、補強コードがテーパ面に露出されている。
