To provide an electric actuator for a landing gear of an aircraft, which achieves weight reduction and facilitation of maintenance.SOLUTION: An electric actuator for a landing gear of an aircraft comprises a slide head mechanism 75 arranged in a casing 50, a motor 51 with a brake, a free-fall gear mechanism 53, a slide shaft, an emergency release mechanism 54, and a rotary connection body 80. The electric actuator has a clutch portion arranged on the slide shaft, and has configuration in which the rotary connection body 80 is tilted by an emergency release solenoid 52 in such a manner that the slide shaft is moved to the inner side, the clutch portion is turned off, an outer peripheral rotation body of the free-fall gear mechanism 53 rotates freely, and a slide head 78 extends outward from the slide head mechanism 75.SELECTED DRAWING: Figure 7

    【課題】軽量化及び整備の容易化を達成するための航空機の降着装置用電動アクチュエータを提供する。【解決手段】航空機の降着装置用電動アクチュエータは、ケーシング50に設けられたスライドヘッド機構75と、ブレーキ付モータ51と、自由落下ギア機構53と、スライドシャフトと、非常用解除機構54と、回動形連結体80と、を備えた航空機の降着装置用電動アクチュエータにおいて、スライドシャフトに設けられたクラッチ部を有し、非常用解除ソレノイド52によって回動形連結体80が傾動してスライドシャフトがその奥側へ移動し、クラッチ部がオフとなり、自由落下ギア機構53の外周回転体が自由回転し、スライドヘッド機構75からスライドヘッド78が外方へ延出するようにした構成である。【選択図】図7
