1. An inspection device for a rotary electric machine, the inspection device comprising:
a base;
a linear motion mechanism mounted to the base for performing linear motion relative to the base through a range of motion;
a link mechanism which has a driving link, and a driven link that is connected to the base, and which extends/contracts relative to the base, by the linear motion performed by the linear motion mechanism, in a direction intersecting a direction of the linear motion;
a connection mechanism for connecting between the driving link of the link mechanism and the linear motion mechanism; and
a sensor mounted to the link mechanism, wherein
the connection mechanism has a link connection portion connected to the driving link, and an interlocking portion that is connected to the link connection portion and that moves in conjunction with the linear motion performed by the linear motion mechanism while being connected with the link connection portion through the range of motion, and
when a force higher than or equal to a predetermined force is applied to the link mechanism, the link connection portion and the interlocking portion are disconnected, and the link connection portion is separated from the interlocking portion so as to contract the link mechanism.
