機き巧こう

noun

trick; contrivance; clever mechanism

Refers to a mechanical trick or clever device, often with a sense of ingenuity. In modern Japanese, からくり is far more common for this meaning; 機巧 is a rare, somewhat literary or technical synonym.

  This clock runs by an ingenious contrivance.

• 彼かれは機き巧こうを凝こらしたおもちゃを作つくるのが好すきだ。
