ABSTRACT:
A shift lever apparatus for an automatic transmission of a vehicle includes shift positions of which are arranged in the order of a parking range, a reverse range, a neutral range, and a drive range and are selectable in a single shift range by a swinging operation of the shift lever. The apparatus is provided with a control member which is adapted to control the movement of a moving plate caused by the pressing of a detent pin. Control is effected such that even if a pushbutton is pressed, a shifting operation from the parking range to another range is prohibited when the parking range is selected as the shift position and a foot brake of the vehicle is not pressed with the foot. Furthermore, even if the pushbutton is pressed, a shifting operation from the neutral range toward the reverse range is prohibited when a speed of the vehicle is above a predetermined value and a shifting operation is effected to the neutral range.
