ABSTRACT:
In a column shift device, a pivot is secured to a shift piece on which a shift lever is supported. A support bore, in which the pivot is rotatably fitted, is provided in a bracket, so that the shift piece can be turned around the pivot to any of a plurality of shift positions. Turning slide surfaces each having a diameter larger than an effective length of the pivot are formed on those opposed surfaces of the bracket and the shift piece which abut against each other in the axial direction of the pivot. Much of load applied to the shift piece is borne by the turning slide surfaces. Thus, even if a relatively short pivot is used, the shift piece can be supported stably on the bracket, and the column shift device can be made compact.
