HORN FOR VEHICLE

PROBLEM TO BE SOLVED: To prevent foreign matters from penetrating a body part of a horn for a vehicle to prevent the foreign matters from penetrating the depth of the horn even when washing the vehicle using high-pressure water or compressed air.SOLUTION: The horn for a vehicle includes: a diaphragm 30; a sound channel 20 which is formed into a spiral path being a propagation path for an oscillatory wave generated by the diaphragm 30; a sound emission part 70 which emits the oscillatory wave propagating in the sound channel 20 to the outside of a body part 40; and a covering reflection plate 80 which is arranged in a ground surface-side position separated from an opening end surface of the sound emission part 70 directed to the ground surface, covers a plane area of the opening end surface of the sound emission part 70 and reflects the oscillatory wave from the sound channel 20 to the outside of the body part 40. A trumpet-shaped front cover 62 forming a front side wall surface of the sound emission part 70 is formed in the body part 40, an overhang plate 63 is provided in the opening end surface of the sound emission part 70, and an edge part 66 projecting toward the covering reflection plate 80 is formed of a lower surface-side rear end part of the overhang plate 63 and an inner wall surface lower end part of the trumpet-shaped front cover 62.
