"1885年3月、新田長次郎氏が大阪府西成郡難波村久保吉、現在の大阪市浪速区にあたる地で製革業を創業した。大阪の製革工場に招かれていたドイツ人技師から、製革は文明社会に必要で発展する事業だと聞かされたことが入口である。創業3年目の1888年5月、英国から機械を導入した大阪紡績の依頼を受け、日本で最初の動力伝動用革ベルトを製造して輸入品への依存を断った。1909年6月に合資会社新田帯革製造所を設立し、タンニン・膠・ゴムベルトへ工程の前後を広げる。1945年2月、事業は新田帯革製造所・新田護謨工業・新田膠質工業の3社へ分割され、現在のニッタは同月に設立された株式会社新田帯革製造所を出発点とする。" }, { "label": "決断", "text": "三度の合弁のうち一つだけを取得し、二つは半分のまま残した。戦後に機械ごとの小型モーターが普及して個別伝動方式へ移ると、集団運転向けの広幅長尺ベルトは主役の位置を失う。1968年7月、米サムエル・ムアーとの合弁でニッタ・ムアーカンパニーを設立し、ナイロン製ホースチューブの技術を導入した。1971年1月には米ユニロイヤルとの折半出資でユニッタを設立して歯付ベルトへ、1983年11月には米ロデールとの合弁で半導体ウエハーの研磨パッドへ入る。1988年にニッタ・ムアーの全株式を取得して完全子会社とし2009年7月に吸収合併した一方、ユニッタとロデール・ニッタは合弁のまま置いた。取得した一社の稼ぎは連結の売上に、残した二社の稼ぎは持分法投資利益に入り、損益計算書の別の行へ分かれた。"
