Abstract
A column shift device for an automatic transmission includes a bracket, and a shift piece turnably connected to the bracket through a first pivot. A shift lever is turnably connected to the shift piece through a second pivot located on a plane substantially perpendicular to the first pivot. A shift link is pivoted on the bracket for operation in association with the turning movement of the shift lever about the first pivot to control the automatic transmission. In the device, a spherical joint member is slidably fitted over an outer periphery of an arm shaft fixedly provided on the shift piece and is slidably engaged in a rectilinear guide groove defined in a shift link. When the shift piece is turned about the first pivot, the joint member is moved rectilinearly along the guide groove. Thus, even if the turning angle of the arm shaft is constant, the turning stroke provided to the shift link by the joint member can be increased.
