Although it has been known that the oil hydraulic jet-pipe servomechanism may often fall into instability, the details of the phenomenon have not yet been clarified. In this study, the instability which occurs in an oil hydraulic jet-pipe servomechanism with a force feedback is treated theoretically and experimentally. The results obtained are summarized as follows : (1) A stability condition of the system is derived. (2) If the condition mentioned above is not satisfied, the system falls into a sustained oscillation, whose amplitude and frequency are uniquely determined by parameters of the system. (3) Under the design condition commonly used, the system is liable to instability. (4) When the jet-pipe is used in a submerged state in oil, flow forces on the jet-pipe appear. And in some cases these forces may cause instability to the system.
