As described above, according to the present invention, in the dual mode shift operating device having the AT mode shift train and the MT mode shift train, the AT mode shift train select lever normally used. A part of the same position as the operation position of the
Switching between the mode and the MT mode is performed electrically by operating a changeover operation switch provided near the knob of the select lever, or mechanically operating manually provided at an operation member or an outer cylinder member provided near the knob of the select lever. By adopting a configuration in which the switching lever is moved by means of a selector lever, the operation stroke of the select lever in the left-right direction is not required, which makes it possible to use it for vehicles such as light vehicles that do not have much room in the vehicle width direction. It is possible to sufficiently apply the mode shift operation device.

Further, in the above, when the AT mode and the MT mode are switched by the movement of the switching lever by the electric switching means or the mechanical switching means by the changeover operation switch, it is interlocked with the movement of the switching lever. The display switching between the AT mode position display such as P, R, N, D, 3, 2, 1 and the MT mode position display such as + and-displayed on the display unit is performed. As a result, it is possible to obtain a very convenient dual-mode shift operating device.

Furthermore, when the MT mode is selected,
By providing D position fixing means for engaging the switching lever and fixing the AT mode side operation system to the D range position, M
The switching from the T mode to the AT mode is always performed accurately and smoothly, and in combination with the simplification of the overall configuration and the reduction in size and size, a great effect can be brought about in practical use. .
