PROBLEM TO BE SOLVED: To restrain an error between a motor command value of a shift controller and a motor rotating position irrespective of an assembling error or the like. SOLUTION: In a princess cam 67, gain change-over parts 67L, 67H of large feedback gain are formed for an oblique rotation angle corresponding to a reference position of a step motor in addition to sloped faces 67a, 67a' corresponding to ordinary feedback gain, and a gain value of the step motor is corrected in response to the oblique rotation angle of the gain change-over part when a detected value of the feedback gain increses. |
