Patent ID: 6848330

Claim:
A gear change device, comprising a shift lever, a select actuator for operating said shift lever in a direction of selection, and a shift actuator for operating said shift lever in a direction of shift, wherein: said select actuator comprises a casing, a shift lever support member disposed in said casing so as to slide in an axial direction while supporting said shift lever, an annular permanent magnet mounted on the outer periphery of said shift lever support member and having magnetic poles in both end surfaces thereof in the axial direction, movable yokes arranged respectively on the outer sides of said permanent magnet in the axial direction thereof, a cylindrical fixed yoke surrounding said magnet, a pair of coil members disposed adjacent each other in the axial direction on the inside of said fixed yoke, and select position-limiting means for limiting the operation position of said shift lever support member in accordance with thrust produced on said shift lever support member due to electric power supplied to said pair of coil members, and said shift lever support member comprises a control shaft rotatably disposed in said casing, and a cylindrical shift sleeve disposed on said control shaft and able to slide in the axial direction, and said select position-limiting means limits the operation position of said shift lever support member so as to position said shift lever to one of four select positions in accordance with thrust produced on said shift lever support member due to electric power supplied to said pair of coil members.
