Abstract
A method for inspecting a rotary machine having a fluid flow path includes a step of connecting an observation device to a connection port having an open/close valve that opens/closes a communication hole that communicates with the outside of the rotary machine and the flow path, the main body being connected to the connection port where the open/close valve is closed; a step of opening the open/close valve and inserting an insertion rod protruding from the main body of the observation device into the communication hole; a step of observing the inside of the flow path by an observation optical system provided at a leading end portion of the insertion rod; a step of withdrawing the insertion rod from the communication hole and closing the open/close valve; and a step of detaching the main body of the observation device from the connection port.
