Zusammenfassung:To provide an electric actuator in which a rotation shaft is connected to a shaft of a water supply controller of a different type.SOLUTION: An electric actuator (10) includes a rotation shaft (50) rotated by a motor (38) via a transmission mechanism, and is installed at the water supply device. A prism part (138) is formed on the top edge of a shaft (128) of the water supply device, a connector 300 includes a pair of leg parts (302) which clamps opposing side faces of the prism part by clamp parts (304), includes step parts (306) severally formed on inner faces of the leg parts above the clamp parts, and the pair of leg parts is connected by a connection part (308) at the top edge. An upper part (308b) of the connection part is fitted with a slit (70) at the bottom edge of the rotation shaft. A stopper (326) is integrally installed on the connection part with a spacing to both faces of the upper part (308b). When the slit (70) covers the upper part (308b), the rotation shaft is fastened from 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(10)は、伝達機構を介してモータ(38)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(138)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(304)で挟む1対の脚部(302)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(306)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
