徴とする展開ラツチ機構。 An arm that is connected to a deployable structure and rotates by the energy of a deployable spring, and a chassis that supports this arm, which is held on the chassis and whose tip is pressed onto a sliding part that is integrally structured with the arm,
In the deployment latch mechanism, which consists of a latch pin that slides as the arm rotates and engages with a latch groove formed on the sliding part at an arbitrary deployment angle, a rigid ball is attached to the tip of the latch pin, and a rigid ball is attached to the surface of the sliding part. The deployment latch mechanism is characterized by being hard anodized and coated with solid lubricant.
