Abstract

A parallel link mechanism is configured so that a plurality of linear actuators which are supported on a base are used to linearly shift one end part of each of links so as to move an end effector coupled to the other end parts of the links. The manipulator further includes a rotation support part that is provided between the end effector and the parallel link mechanism and that supports the end effector rotatably around a predetermined rotational axis, and a hydraulic drive mechanism that generates in the end effector rotating power around the rotational axis. The manipulator imparts, from the exterior to the hydraulic drive mechanism, change in the working-fluid hydraulic pressure so as to generate movement for rotating the end effector.
