Actuator

It is based on the English word meaning "drive device" and is something that "converts input energy into physical motion". The input energy can be human power, air, hydraulic pressure, or electricity, and the most typical example is a motor that converts electricity into rotary motion. In the case of robots, etc., in addition to electric actuators, mechanical parts that convert hydraulic pressure and air sent from air cylinders into motion are also called. In addition, in the case of connectors, the locking mechanism of FPC connectors, such as front flip and back flip, is sometimes called so in the sense that human power is converted into action = function, and it has become established in some areas.
