Patent ID: 7222554

Claim:
A shift actuator for a transmission, said shift actuator comprising: a shift lever support mechanism mounting a shift lever of the transmission; an operation lever having an intermediate portion coupled to said shift lever support mechanism; a first actuator having an operation rod pivotally coupled to one end of said operation lever and operable in an upward direction, to push said one end of said operation lever upward, causing pivoting of said shift lever support member in a first angular direction, and operable in a downward direction, to pull said one end of said operation lever downward, causing pivoting of said shift lever support member in a second angular direction, opposite the first angular direction; a second actuator having an operation rod pivotally coupled to the other end of said operation lever and operable in an upward direction, to push said other end of said operation lever upward, causing pivoting of said shift lever in the second angular direction, and operable in a downward direction, to pull said other end of said operation lever downward, causing pivoting of said operation lever support member in the first angular direction, wherein: each of said first actuator and said second actuator comprises a magnetic moving member on an outer peripheral surface of said operation rod, a cylindrical fixed yoke surrounding said magnetic moving member, and a pair of coils arranged side by side in the axial direction of said operation rod inside said fixed yoke.
