ABSTRACT:
Present invention relates to a measuring device which is capable of improving anti-vibration property and anti-impact property. The measuring device comprises a case 1, a spindle 11 displaceably provided to the case 1, a sensor on stationary side attached to the case 1 through a base 33 and a sensor on movable side formed on a scale 35 attached to the spindle 11, and a relative displacement amount of the two sensors 32 and 34 opposing at a predetermined gap G therebetween. A gap enlargement limiting pin 41 is provided on the side of the spindle 11 to restrict a fluctuation of the gap G caused by vibration of the spindle 11 and the like within a predetermined allowance, and a gap reduction limiting film 42 is provided to the sensor on stationary side 32.
