A manipulator usable for a glass electrode or the like comprises roughly moving mechanisms for roughly moving the glass electrode not only in the longitudinal and lateral directions but also in the heightwise direction, as well as a finely moving mechanism for finely moving the glass electrode in the longitudinal and lateral directions. It further comprises an operation lever, which is provided interiorly with a hydraulic cylinder capable of being pushed by a piston interlocking with an operation knob. A base member and a slider slidable in the heightwise direction relative thereto are incorporated into any one of the roughly moving mechanisms. Between the base member and the slider there are disposed a piston and a second hydraulic cylinder, said second hydraulic cylinder being connected to the hydraulic cylinder within the operation lever. |
