To provide a steel cord which is difficult to break when external force is applied.SOLUTION: The steel cord is a single-track steel cord and includes a brass plating film on its surface. A cord diameter D is 0.20 mm or more and 0.42 mm or less. The steel cord includes a bent part and a non-bent part along a longitudinal axis in alternately repeated fashion. It forms three continuous bent parts including a first bent part, a second bent part and a third bent part in order along the longitudinal axis. The steel cord is configured so that an inflection height H and the cord diameter D satisfy the relationship of 2.2≤H/D≤2.8 when the distance between a peak of the second bent part and a straight line which comes into contact with a peak of the first bent part and a peak of the third bent part is defined as the inflection height H.SELECTED DRAWING: Figure 2
【課題】外力が加わった際に破損しにくいスチールコードを提供する。【解決手段】単線のスチールコードであって、表面にブラスめっき膜を有し、コード径Dが0.20mm以上0.42mm以下であり、長手軸に沿って、屈曲部と非屈曲部とを交互に繰り返し有しており、連続する3つの前記屈曲部を、前記長手軸に沿って順に第1屈曲部、第2屈曲部、および第3屈曲部とし、前記第2屈曲部の頂点と前記第1屈曲部の頂点および前記第3屈曲部の頂点に接する直線との間の距離を屈曲高さHと定義すると、前記屈曲高さHと前記コード径Dとは、2.2≦H/D≦2.8の関係を満たす、スチールコード。【選択図】図2
