(54) Horn for vehicle


(57) The horn is capable of preventing invasion of foreign matters and highly preventing attenuation of a warning sound. The horn (10) comprises: an oscillation member (20); a sound path (30) formed into a spiral path, which is spirally formed around a center axis (22) of the oscillation plate (20) and in which a distance from the center axis (22) is gradually increased toward an outer end; and a sound output section (70) provided to the outer end of the sound path (30), the sound output section (70) outputting sound waves, which have passed through the sound path (30), in the axial direction of the center axis. The horn is characterized in that an opening part of the sound output section (70) has an elongate configuration, whose long axis is arranged in the vertical direction.
