A digital displacement measuring instrument includes a spindle (2) screwed into a body (10) to be axially advanced and retracted relative to the body (10); and an encoder (40) that detects a displacement of the spindle (2). The encoder includes a rotor (41) and a stator (42). The rotor is supported by a rotor bushing (44). The rotor bushing includes an engaging key (43) engageable with a key groove (23) axially provided on the outer circumference of the spindle (2), and is displaced in the axial direction of the spindle (2) via a position adjusting screw (51). The stator is fixed to the body via a stator bushing (45) in the vicinity of the spindle so as not to be displaceable in the axial direction of the spindle. |
