Abstract: An inspection device inspects an inspection target part by being inserted into a gap between an inner circumferential surface of a stator and an outer circumferential surface of a rotor of a rotary electric machine. The inspection device includes: a traveling body which is attached to a base frame and moves the base frame in an axial direction in the gap; a probe which inspects the inspection target part; a radial-movement portion which moves the probe in a radial direction perpendicular to the axial direction and a circumferential direction; and a circumferential-movement portion which moves the probe in the circumferential direction in the base frame.

Abstract: A rotary electric machine examination device of the present disclosure includes: first and second base units attached to both ends of rotor retaining rings fixed to both axial end sides of a rotor; a guide wire stretched between the first and second base units; an inspection unit which moves on the stator and includes a housing having both side surfaces restricted by the guide wire, and a sensor unit; and a driving rope which drives the inspection unit in the axial direction. The guide wire is stretched such that the distance between the guide wire and the rotation axis at the positions of the first and second base units is greater than the distance between the guide wire and the rotation axis at the position of the inspection unit.
