Abstract: A 2-L slider supported by a shaft so as to be slidable in a predetermined range substantially in a vehicle transverse direction that, when pressed by a shift lever which is being a select-operated to an “L” position, slides toward a detent wall against an urging force of a compression coil spring. At this time, a cam portion provided at the 2-L slider presses a press receiving block provided at a shift lock plate downward. Thus, a slider which slides with the shift lock plate moves downward. A position detecting mechanism detects that the slider has moved downward. The position detecting mechanism is not a mechanism specially provided for detecting select operation to the “L” position, but a mechanism for detecting whether or not the shift lever is positioned at a “P” position. Therefore, costs can be kept down.
