ABSTRACT:
An articulation mechanism which can change a hinge angle freely, even if a considerable large load is attached to the tip end of a movable arm, and which can hold the hinge angle rigidly, when it is once stopped, is provided. The articulation mechanism (1) has a fluid hermetically sealing space (25) in which a non-compressive fluid or a compressive fluid compressed to a predetermined pressure is hermetically sealed, so that even if there may be energizing force, relative rotation between rotary members is prevented by a predetermined force. When the fluid hermetically sealing space is released by opening and closing valve (21), as a result of the energizing force such as may be generated, for example from load or spring, the fluid can transfer, resulting in relative rotations of the rotary members. When the opening and closing valve (21) is in closed state, the fluid hermetically sealed in the sealing space (25) does not permit a change in distance between each of local portions of the respective rotary members. As a result, relative rotations of the rotary members are prevented.
