Abstract
In an electric actuator having inner component parts thereof inclusive of a motor 1 covered with a cover main body 10, the cover main body 10 having a coating (protection) function serves as a manually operating part and is equipped with a mechanism for switching between electrical and manual operations. A fixing structure for connecting and fixing an electrical actuator 40 and a rotary valve 23 includes an annular one-way clutch structure 25 at one of the opposite fixing positions, and includes an annular face part 6 disposed at the other of the opposite fixing positions. The annular face part 6 is inserted into the one-way clutch structure 25, thereby restraining the actuator and valve from being rotated in one circumferential direction.
