Abstract:
A gear change device comprising:a select actuator for operating the shift lever of a transmission in the direction of selection; and a shift actuator for operating said shift lever in the direction of shift; wherein said select actuator has a casing, a shift lever support member that is arranged in said casing so as to slide in the axial direction and supports said shift lever, a magnetic moving means arranged on the outer periphery of said shift lever support member, a cylindrical fixed yoke arranged surrounding said magnetic moving means, a pair of coils arranged inside said fixed yoke, and a select position-limiting means for limiting the operation position of said shift lever support member according to a thrust produced by said shift lever support member in proportion to the amount of electric power fed to said pair of coils; and further, magnetic members are arranged on both sides of said pair of coils for exerting a force on the shift lever support member due to a magnetic force created by the magnetic moving means.
