A piston is displaced by a pressure fluid supplied to a chuck body, whereupon a pair of first and second fingers that constitute a gripping member are operated to open and close along a base body. Further, a shaft-shaped bobbin is inserted through the interior of the first and second fingers, and a coil is wound around a small diameter portion of the bobbin. Accompanying opening/closing operations of the first and second fingers, an opening/closing amount thereof is detected based on a change in impedance of the coil.

Chuck apparatus

Rotational motion of a male screw member is converted to linear motion of a female screw member that is screw engaged with the male screw member, thereby causing movement of a rod member for clamping an object. When a load from the object becomes larger than a predetermined value, and exceeds the frictional force of a viscous material and a friction plate, the female screw member is gradually turned and clamping continues while movement of the rod member is decelerated.
