A gauge 4 includes a contactor 4α that contacts each surface of the actuator 4 and 3, and emits an electric signal to indicate the sliding distance of the actuator. Arm member 6 driven in the direction of arrow Z and its opposite direction
and a comparator 7 that receives a signal from the gauge 4 and determines whether the distance between surfaces is acceptable or not. In the distance measuring device having such a configuration, the scale of the gauge 4 can be visually recognized, and if the comparator 7 is one that displays the movement of the pointer of the gauge 4, each small part can be identified by looking at this display. It is possible to know a few interplanar distances for individual electronic components.
