摘要：【課題】圧接部の高摩擦係数と摺接部の低摩擦係数を両立できる高効率な自動変速機を提供する。【解決手段】本発明の自動変速機は、対向する一対の圧接面を有する圧接部と、対向する一対の摺接面を有する摺接部と、圧接面間および摺接面間に介在する作動潤滑油とを備える。摺接面の少なくとも一方は、Bを含有した非晶質炭素膜(以下「B−DLC膜」という。)により被覆されている。作動潤滑油は、Mo:50ppm以下およびZn:50ppm以下であると共に、B:90〜300ppmを含む。作動潤滑油はMoやZnを含まないため、B−DLC膜で被覆されていない圧接部で高摩擦係数が確保される。一方、Bを従来よりも多く含む作動潤滑油と摺接面を被覆するB−DLC膜とが相乗的に作用することにより、摺接部における摩擦係数を大幅に低減できる。こうして本発明によれば、従来よりも低損失で高効率な自動変速機を提供できる。【選択図】図3
