This disclosure depicts a drivably connecting construction in a measuring instrument for connecting a main body of measuring instrument to a nut member threadably coupled to a feed screwshaft, including: a first engaging device (28) in which a connecting plate (24) is loosely coupled onto a nut member (21) and this connecting plate (24) is clamped from opposite sides in the feeding direction through balls (25); a second engaging device (39) for tiltably connecting a portion of the connecting plate (24) to the side (14) of the main body of measuring instrument; and a third engaging device (48) for clamping an arm (41) protruded from the nut member (21) through balls (45) to thereby make the nut member (21) unrotatable relative to the main body of measuring instrument. |
