Zusammenfassung:PROBLEM TO BE SOLVED: To provide a disengagement device which can reduce backlash upon separation, and also reduce operational ability for disengaging connection, compared with the conventional art.SOLUTION: A disengagement device 1 for disengaging linkage of an automatic steering system comprises: an operation cable 140 which is operated by a pilot; a rotor 2 and a stator 3 which are arranged in parallel along an axial direction, and disengage and establish linkage by being separated from and coupled to each other; three keys 4 which are rotatably supported by the stator 3, and make the rotor 2 and the stator 3 coupled to each other by being engaged to the rotor 2 in accordance with rotation in one direction; a spring 5 which energizes the three keys 4 in the one direction; and a fork 6 formed in a long manner and supported rotatably around an upper fixed shaft 62a, which presses the three keys 4 against an energizing force of the spring 5 in a direction opposite to the one direction in accordance with rotation in association with operation of the operation cable 140 when the operation cable 140 is connected to a lower fixed shaft 62b.SELECTED DRAWING: Figure 4 【課題】従来に比べ、バックラッシュを低減させるとともに、連結解除に要する操作力も低減させる。【解決手段】ディスエンゲージ装置1は、自動操縦系統のリンケージを解除するものであり、パイロットに操作される操作ケーブル140と、軸方向に沿って並設され、互いの分離・結合によりリンケージを解除・成立させるローター2及びステーター3と、ステーター3に回転可能に支持され、一方向の回転に伴ってローター2に係合することによりローター2及びステーター3を互いに結合させる3つのキー4と、3つのキー4を一方向に付勢するスプリング5と、長尺に形成されて上部固定軸62a回りに回転可能に支持されるとともに下部固定軸62bに操作ケーブル140が接続され、操作ケーブル140の操作に連動した回転に伴って、3つのキー4をスプリング5の付勢力に抗して一方向とは反対方向に押圧するホーク6とを備える。【選択図】図4
