ABSTRACT:
A back-plunger type displacement detecting apparatus is provided having a thinner case. The back-plunger type displacement detecting apparatus has a spindle secured to the case to extend perpendicular to the display surface of a digital display unit. A movable member is secured to the case and extends perpendicular to the direction of movement of the spindle. A converting mechanism converts the displacement of the spindle into displacement of the movable member. An electrical unit detects the displacement of the movable member and displays the detected value on the digital display unit.
