PROBLEM TO BE SOLVED: To make it possible to miniaturize in radial direction of the input-output shaft so that it makes the input-output gear ratio nearly 1:1 at the time of actuator stoppage. SOLUTION: In the power transmission capable of changing the relation between the operation quantity on the input side and the working quantity of the output side freely, an input gear 14 and an output gear 15 are arranged facing to the same axial line, and a revolving support member 16 is arranged rotatably around the revolving axial center line of these gears between the input gear 14 and the output gear 15. An intermediate gear 21 supported rotatably around an axial line that crosses to a revolving axial center line of the input and the output gear 14, 15 crossed from a support member 16 is engaged with the input gear 14 and the output gear 15 at the same time, and it constitutes so that a ring member 20 arranged concentrically and integrally with the support member 16 is revolved and stopped by an electric motor 23.
