[0054]

As described above, according to the present invention, in a dual mode shift operating device having an AT mode shift train and an MT mode shift train, a normally used AT mode shift train select lever is used. A part of the same position as the operation position is used as a shift train for the MT mode.
The switching between the mode and the MT mode is performed by an electric means by operating a switching operation switch provided near the knob of the select lever or a mechanical means by manually operating an operating member or an outer cylinder member provided near the knob of the select lever. The shift lever is moved by the switch lever, which eliminates the need to operate the select lever in the left-right direction. The mode shift operating device can be sufficiently applied.

In the above, when the switching between the AT mode and the MT mode is performed by the movement of the switching lever by the electrical switching means or the mechanical switching means by the switching operation switch, the movement of the switching lever is interlocked. Thus, display switching between the position display for the AT mode such as P, R, N, D, 3, 2, and 1 displayed on the display unit and the position display for the MT mode such as + and-is performed. This makes it possible to obtain a very convenient dual-mode shift operation device.

Further, when the MT mode is selected,
By providing a D position fixing means for engaging the switching lever and fixing the AT mode side operation system to the D range position,
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 miniaturization, a great effect can be brought about in practical use. .
