A ship equipped with a steam engine as its propulsion system. At the beginning of the 19th century, steam engines were first put to practical use as ship propulsion systems, and since then, all early propulsion systems were steam engines, so ships equipped with these were called steamships, or simply "steamships." Later, other types of engines, such as internal combustion engines, began to be used on ships, and the term "steamship" came to refer to all ships propelled by mechanical power. The Ship Law Enforcement Regulations state that "A ship equipped with a device for operating by mechanical power is considered to be a steamship, regardless of whether it uses steam or not."

推進機関として蒸気機関を備えた船。19世紀の初め、船の推進機関として蒸気機関が最初に実用化され、それ以来、初期の推進機関はすべて蒸気機関であったことから、これを装備した船を蒸気船といい、略して汽船といった。その後、内燃機関など他種の機関が船に使用されるようになって、汽船という名称は、機械力で推進する船すべてをさすようになった。船舶法施行細則には「機械力をもって運航する装置を有する船舶は、蒸気を用いると否とにかかわらず、これを汽船とみなす」と定められている。 [森田知治] [参照項目] |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 |
