PROBLEM TO BE SOLVED: To provide a solid wire cord, a rubber cord composite and a tire which can improve strength while preventing mass increase.SOLUTION: A solid wire cord 13 includes: a hollow part 15 locating in center of a cross section which is right angle to a longer direction; a ring-like body part 16 having substantially fixed wall thickness t and surrounding the hollow part 15; and several projecting parts 17 projecting from the body part to the outside to the radial direction. In the solid wire cord 13, each of the several projecting parts 17 is desirable to be formed in the circumferential direction of the body part 16 every uniformity, and maximum height Ha of each several projection parts 17 from the body part 16 is desirable to be smaller than the wall thickness t of the body part 16.SELECTED DRAWING: Figure 3
【課題】質量増を抑制しつつ強度を向上させ得る単線コード、ゴム・コード複合体及びタイヤの提供。【解決手段】長手方向と直角な横断面において、中心に位置する中空部15と、実質的に一定の肉厚tを有して中空部15を囲むリング状の本体部16と、本体部から半径方向外側に突出する複数の突部17とを含んでいる単線コード13。各突部17は、本体部16の円周方向に、一定の間隔で形成されているのが望ましく、各突部17の本体部16からの最大高さHaは、本体部16の肉厚tよりも小さいのが望ましい単線コード13。【選択図】図3
