To provide an alarming horn for a vehicle that achieves both coupling stability in manufacture and life improvement.SOLUTION: An alarming horn 1 for a vehicle comprises a first high hardness part 22a having a higher surface hardness than a base material of a fixed iron core 22 and a second high hardness part 4a having a higher surface than a base material of a movable iron core 4. The first high hardness part 22a is provided at least on an end of the fixed iron core 22 facing the movable iron core 4 in an axial direction. The second high hardness part 4a is provided at least on an end of the movable iron core 4 facing the first high hardness part 22a in an axial direction. This makes it possible to reduce wear due to impact of the movable iron core 4 and the fixed iron core 22. The repetition of the impact can prevent a movement distance of the movable iron core 4 with respect to the fixed iron core 22 from being increased. The alarming horn 1 for a vehicle thus can achieve life improvement.SELECTED DRAWING: Figure 1

    【課題】製造上の結合安定性と寿命向上との両立が図れる車両用警音器を提供する。【解決手段】車両用警音器1は、固定鉄心22の母材硬度よりも高い表面硬度である第1高硬度部22aと、可動鉄心4の母材硬度よりも高い表面硬度である第2高硬度部4aとを備える。第1高硬度部22aは、可動鉄心4に対して軸方向に対向する固定鉄心22の端面に少なくとも設けられている。第2高硬度部4aは、第1高硬度部22aに対して軸方向に対向する可動鉄心4の端面に少なくとも設けられている。これにより、可動鉄心4と固定鉄心22の衝突に伴う磨耗を抑えることができる。衝突の繰り返しにより、固定鉄心22に対する可動鉄心4の移動距離が増加することを抑制できる。車両用警音器1は寿命向上が図ることができる。【選択図】図1
