PROBLEM TO BE SOLVED: To provide a vehicle alarming horn capable of suppressing the characteristic change of the horn.SOLUTION: A vehicle horn 1 includes a coil 20, a fixed iron core 22 which generates magnetic attraction force by magnetic force generated from the coil 20, and a movable iron core 4 which is displaced in the axial direction with respect to the fixed iron core 22 due to a magnetic attraction force generated from the fixed iron core 22. A fixed contact portion 80 is in a sliding relationship relative to the movable iron core 4. The movable iron core 4 includes an energization portion 42 which is in a conducting state in which a current flows through the coil 20 when the fixed contact portion 80 contacts it, and a non-conducting portion 43 which is in a non-conducting state in which no current flows through the coil 20 when the fixed contact portion 80 is displaced to a position where it does not contact the energization portion 42. The non-conducting portion 43 is provided at a position shifted in the axial direction with respect to the energization portion 42 in the movable iron core 4.SELECTED DRAWING: Figure 2
【課題】ホーンの特性変化を抑制できる車両用警音器を提供する。【解決手段】車両用警音器1は、コイル20と、コイル20から発生する磁力によって磁気吸引力を発生する固定鉄心22と、固定鉄心22から発生する磁気吸引力によって固定鉄心22に対して軸方向に変位する可動鉄心4とを備える。固定接点部80は、可動鉄心4に対して相対的に摺動関係にある。可動鉄心4は、固定接点部80が接触することでコイル20に電流が流れる通電状態となる通電部42と、固定接点部80が通電部42に接触しない位置に変位することでコイル20に電流が流れない非通電状態となる非通電部43とを備える。非通電部43は、可動鉄心4において通電部42に対して軸方向にずらした位置に設けられている。【選択図】図2
