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 includes a rotating shaft 50 rotated by a motor via a transmission mechanism and is attached to a water supply device. A prismatic portion 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 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 308 at an upper end. An upper portion 308b of the connecting part fits into a slit 70 at a lower end of the rotating shaft. A stopper 326 is integrally mounted on the connecting part at intervals from both sides of the upper portion 308b. When the upper portion 308b is covered with the slit 70, the rotating shaft is restrained from the outside by the stopper 326.SELECTED DRAWING: Figure 15 【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の上端には角柱部が形成される、連結具３００は、角柱部の対向する側面を挟み部で挟む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３０８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７０に嵌まり合う。上部分３０８ｂの両面と間隔を隔てて連結部上に一体的にストッパ３２６は取り付けられる。上部分３０８ｂにスリット７０を被せたとき、回転軸がストッパ３２６によって外側から拘束される。【選択図】図１５
