子式光路自動補償機構。 In a pendulum-type automatic optical path compensation mechanism for a surveying instrument in which a pendulum body with a reflecting mirror attached to a fixed side frame fixed to the body casing of the surveying instrument is suspended by a suspension wire, the suspension wire is a thin strip suspension wire. At the same time, holes for setting the pendulum length are formed at both ends of the hanging wire at a certain distance, and on the other hand,
The fixed side frame body and the pendulum body are made of thermoplastic resin, and an engaging protrusion that engages with the hole on the hanging wire side is formed protrudingly on the suspension wire support surface of the stationary side frame body and the pendulum body. A pendulum-type optical path automatic compensation mechanism for a surveying instrument, characterized in that the tip of the engaging protrusion is heat-treated by heat caulking or the like, and the peripheral edge of the hole of the hanging wire is held between the hanging wire clamping surfaces.
