Abstract
A method for inspecting a rotary machine having a flow path through which a fluid flows includes a step of measuring a width of the flow path by a non-contact sensor in a stationary component of the rotary machine at a position facing the flow path; and a step of determining whether or not the measured width of the flow path is less than a predetermined lower limit threshold.
