ABSTRACT:
A parallel mechanism adapted to control at least one of pivotal movement and linear movement of a link head having three degrees of freedom. The parallel mechanism has four actuators for driving the link head, and link groups which have four links connected to the four actuators, respectively, and each of which is connected to the link head. A rotation joint interposed between each of the link groups and the link head is made a linear joint which is connected to the link head so as to be relatively movable in one axis direction with respect to the link head.
