PURPOSE:To surely hold several kinds of circular bodies such as capacitors or the like whose outside diameters are different and to execute a operation and an inspection in various processes in a state that they are held by a method wherein, as a turning body is turned, a plurality of gripping pins are moved inside long hole parts and a diameter of a fitting part, of the circular bodies, constituted of the plurality of gripping pins is constituted so as to be made large. CONSTITUTION:A diameter of a capacitor fitting part A constituted of four gripping pins 26 is made smallest by using an expansion spring 32; the pins are situated at points (a) in four long hole parts 27; when a turning body 24 is turned in an arrow direction from this state by holding an operating knob 28, the four long hole parts 27 are turned also in the arrow direction; four rocking bodies 22 are also turned clockwise around pins 23. By this turning operation, the four gripping pins 26 are moved relatively inside the four long hole parts 27 and expand the expansion spring 32 which is wound at the outside of the four gripping pins 26. A capacitor is inserted into the fitting part A; the four gripping pins 26 are brought into contact with an outer wall of the capacitor; this capacitor is held by a springy force of the expansion spring 32. |
