る自動補償装置。 A pendulum with a correction reflecting surface always facing the horizontal direction in the observation optical path regardless of the inclination of the device body is suspended from the device body, and a swing range regulating device is provided to limit the swing range of the pendulum. In the automatic compensation device for a surveying instrument, a pair of limit spring members are disposed at a predetermined distance from the pendulum in the direction of swing of the pendulum and are deformed in the direction of swing of the pendulum; An automatic compensation device characterized in that the swing range regulating device includes a blocking member that blocks movement of the pendulum when a spring member is deformed by a predetermined amount.
