1. An inspection apparatus which, when an inspection is performed on a rotary electric machine in which an air gap is interposed between a rotor and a stator, and a ventilation hole along a radial direction of the rotor is formed in the rotor, is inserted into the air gap, and adheres to the stator, and travels along an axial direction of the rotor, the inspection apparatus comprising:
a rotor image-pickup unit for picking up an image of the rotor using a rotor image-pickup device in the air gap, wherein
the rotor image-pickup device comprises:
a carriage casing;
a camera installed in the carriage casing, and configured to pick up an image of the ventilation hole of the rotor;
an image-pickup position changing part installed in the carriage casing, and configured to change an image-pickup position of the camera by moving the carriage casing in a circumferential direction of the rotor; and
an image-pickup direction changing part installed in the carriage casing, and configured to change an image-pickup direction of the camera to an inclined angle to the radial direction of the rotor, with the axial direction serving as a support axis.
