To provide a vehicular horn capable of suppressing an axial load in relation to a fixing structure of a fixed core and a stay, and not requiring a part such as a bolt nut fastening.SOLUTION: A fixed core 5 has a columnar projecting portion 50 projecting to the outside of a housing in a state of being inserted into a through hole 60 of a stay 6 and a locking portion 52. The locking portion 52 contacts the stay 6 so as to push an open end portion 61 of the stay 6 forming the axial end portion of the through hole 60 in the radially outward direction in a state in which the portion of the projecting portion 50 located outside the stay 6 is plastically deformed so as to protrude in the radially outward direction. The projecting portion 50 is formed so that the outer diameter SD2 of a distal end side portion 50a located outside the locking portion 52 in the axial direction of the fixed core 5 is smaller than the outer diameter SD1 of a proximal end portion 50b located inside the through hole 60.SELECTED DRAWING: Figure 8
【課題】固定鉄心とステーの固定構造に関して軸方向荷重の抑制が図れ、ボルトナット締め等の部品を必要としない車両用警音器を提供する。【解決手段】固定鉄心5は、ステー6の貫通孔60に挿通された状態でハウジングの外部に突出する柱状の突出部50と係止部52とを有する。係止部52は、ステー6よりも外側に位置する突出部50の一部が径外方向に突出するように塑性変形した状態で、貫通孔60の軸方向端部を形成するステー6の開口端部61を径外方向に押すようにステー6に接触する。突出部50は、係止部52よりも固定鉄心5の軸方向外側に位置する先端側部位50aの外径SD2が貫通孔60の内側に位置する基端側部位50bの外径SD1よりも小さくなるように、形成されている。【選択図】図8
