うにしたことを特徴とするサーボ装置の安全機構
。 A servo spool that provides a target position, an output member that is slidably fitted into the servo spool, and a biasing force that is generated by using the relative displacement between the output member and the servo spool, and the biasing force causes the output member to servo. In a servo device comprising a hydraulic drive mechanism that follows a spool, a stopper is provided to give a stroke end to the servo spool, and when the servo spool is fixed to the output member with fluid, the output member reaches the operating end. A safety mechanism for a servo device, characterized in that the servo spool is stopped in advance by its stopper.
