PROBLEM TO BE SOLVED: To provide a warning sound alarm for vehicle which can suppress variation of timbre with collision of a fixed core and a moving core.SOLUTION: A warning sound alarm for vehicle 1 comprises: a coil 20; a fixed core 22 generating magnetic attraction force by magnetic force from the coil 20; a moving core 4 displacing axially for the fixed core 22 by the magnetic attraction force; and a diaphragm 3 vibrating with displacement of the moving core 4. The moving core 4 comprises a shock absorption part 5 comprised of a material softer than the moving core 4 and the fixed core 22 at the distal surface 40 facing to the axial direction for the fixed core 22. The warning sound alarm for vehicle 1 which can suppress variation of timbre with collision of a fixed core 22 and a moving core 4 can be provided by the shock absorption part 5.SELECTED DRAWING: Figure 1

    【課題】固定鉄心と可動鉄心の衝突に伴う音色の変化を抑制可能な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からの磁力によって磁気吸引力を発生する固定鉄心22と、この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、可動鉄心4の変位に伴って振動する振動板3と、を備える。可動鉄心4は、固定鉄心22に対して軸方向に面する先端面40に、可動鉄心4および固定鉄心22よりも柔らかい素材で構成されている衝撃吸収部5を備えている。この衝撃吸収部5によれば、固定鉄心22と可動鉄心4の衝突に伴う音色の変化を抑制可能な車両用警音器1を提供できる。【選択図】図1
