A device used on railroad cars and ships to emit warning or signal sounds. In railroad terms, it is called a horn. On steam locomotives, the whistle is generated using steam pressure, so it has come to be commonly known as a steam whistle. The same is true for steamships. Electric locomotives and trains use compressed air to generate the sound. Electronic whistles are also used.

鉄道車両や船舶などで、警報音や合図音などを発生させる装置。鉄道の専門語としては警笛。蒸気機関車では蒸気圧を利用して吹き鳴らしたので、汽笛の俗称で普遍化した。汽船の場合も同じである。電気機関車や電車などは圧搾空気を利用して吹き鳴らす。電子音のものも採用されている。 [西尾源太郎・佐藤芳彦] 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
