Abstract
An electric actuator has a motor, an electricity storing body, a switch and a resetting unit. The switch is provided in a supply path of electric power from the electricity storing body to the motor. The switch opens the supply path for electric power from the electricity storing body to the motor, in response to an instruction from an operator. The resetting unit is operated through receiving a supply of electric power from the external power supply when the external power supply has been restored from being cut off. The resetting unit closes the switch that is provided in the supply path of electric power from the electricity storing body to the motor.
