ELECTRIC ACTUATOR
To provide an electric actuator that connects a rotating shaft to a shaft of a different type of a water supply control device.SOLUTION: An electric actuator 10 includes a rotating shaft 50 rotated by a motor via a transmission mechanism and is attached to a water supply device 104. A prismatic portion 138 is formed at an upper end of a shaft 128 of the water supply device. A connector 300 includes a pair of legs that sandwich opposing side surfaces 140 of the prismatic portion with sandwiching portions, and includes stepped portions respectively formed on inner surfaces of the respective legs above the sandwiching portions, and the pair of legs are connected by a connecting part at an upper end. An upper portion 308b of the connecting part fits into a slit at a lower end of the rotating shaft. At an upper end portion of the shaft, a nut 146 protruding in a direction orthogonal to the axial direction of the shaft engages with the stepped portion to prevent the connector, that is, a water supply control device from coming off the shaft 128.SELECTED DRAWING: Figure 9
【課題】回転軸を異なる形式の送水制御装置のシャフトに連結する電動アクチュエータを提供する。【解決手段】電動アクチュエータ１０は、伝達機構を介してモータによって回転される回転軸５０を含み、給水装置１０４に取り付けられる。給水装置のシャフト１２８の上端には角柱部１３８が形成される。連結具３００は、角柱部の対向する側面１４０を挟み部で挟む１対の脚部を含み、挟み部より上の脚部の内面にそれぞれ形成された段差部を含み、１対の脚部は上端において連結部で連結される。連結部の上部分３０８ｂが回転軸の下端のスリットに嵌まり合う。シャフトの上端部においてシャフトの軸方向に直交する方向に突出したナット１４６が段差部と係合することによって、シャフト１２８から連結具すなわち送水制御装置が抜けるのが防止される。【選択図】図９
