Abstract
There is provided a rotary actuator which makes it possible to operate a regulation release of a regulating member from the outside of a case body when the regulating member is in a regulation position, and can prevent an unexpected regulation release, and a robot. A drive mechanism of a joint part has a compression coil spring for biasing a regulation pin toward a regulation position, and a solenoid for moving the regulation pintoward a regulation release position. A through hole is formed in a case body at a portion facing the upper end portion (the other end portion opposite to one end portion abutting against the regulation pin) of a plunger of the solenoid, and the upper end portion of the plunger is positioned on the inside of the case body while the regulation pin is in the regulation position.
