摘要：

PROBLEM TO BE SOLVED: To provide an examining device for the internal structure of a turbine capable of reducing procedure of disassembly of a device and quantitatively examining circumstances of a turbine nozzle in the inspection of the inside of the device, especially, the inspection of a nozzle and a moving blade in a turbine.

SOLUTION: In the examining device constituted of a video probe and a carrier for carrying the video probe, and examining the internal structure of the turbine by inserting the video probe in the turbine, the carrier includes at least either a mechanism for deciding the advancing direction of the carrier and a facing angle of the tip of the video probe or a mechanism for deciding the positions of the axle of the carrier and the video probe. The circumstances of the turbine nozzle are quantitatively examined by making the carrier stably travel along a blade line in such a state that at least either the advancing direction of the carrier and the facing angle of the tip of the video probe or the positions of the axle of the carrier and the video probe is decided.
