PROBLEM TO BE SOLVED: To provide a measuring method and a measuring apparatus of deflection of a revolving shaft capable of measuring efficiently the deflection of the revolving shaft under revolution, even when a sensor cannot be installed in a vertical direction to the axis (central axis) of the revolving shaft.SOLUTION: In a measuring method of deflection of a revolving shaft, a displacement magnitude of a shaft end face vertical to the axis of the revolving shaft is measured during revolution of the revolving shaft, and deflection of the revolving shaft under revolution is operated/calculated from a measured value. 【課題】回転軸の軸心（中心軸）に垂直な方向にセンサを設置できない場合でも、回転中の回転軸のたわみ量を効率的に測定することができる、回転軸のたわみ量測定方法および測定装置を提供する。【解決手段】回転軸の回転中に、回転軸の軸心に垂直な軸端面の変位量を測定し、その測定値から回転中の回転軸のたわみ量を演算・算出することを特徴とする回転軸のたわみ量測定方法。【選択図】図１
