BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever device, and more particularly to a transformer type shift lever device capable of giving a driver a tactile sense of a shift state and information related thereto.

In general, development of high-fuel-efficiency vehicles is inevitable due to high oil prices and environmental regulations, and various developments are being carried out.

As an example to improve the fuel efficiency, there is a technique that informs the driver of the optimal shift point for fuel economy improvement.

As an application technique for this, an optimal shift point for improving fuel efficiency is determined as a logic for a driver, and the driver is notified of this point of time as a visual signal in a cluster or an audible signal such as an alarm sound to inform the driver, There is a way to provide judgment about the operation.

However, such a method can not provide undesirable inconvenience by providing the driver with visual or auditory sense while driving.

For example, the method of informing the driver of the shift time point by the visual signal may disperse the driver's front view visibility unintentionally. In particular, when the driving mode state is transmitted to the driver using the cluster window, It becomes more and more difficult.

In addition, the method of informing the driver of the shifting point by the audible signal not only can cause discomfort to the driver, but also reduces the driver's cognitive ability when it overlaps with other indoor noise of the driving vehicle.

On the other hand, the shift lever is a means for changing the position of a shift stage desired by a driver by changing its position along a gate pattern indicating a shift unit value, and is a means for normally protruding from a gate pattern (gate pattern) .

As described above, the shift lever is a part where a manual operation is always required to be performed by hand for shifting, particularly in a manual transmission, and the driver must feel the touch of the shift lever most intimately without any sense of resistance.

Therefore, if the shift lever is used to provide the driver with the optimum shift time point for improving the fuel efficiency of the vehicle, there is a convenience of providing the function without deteriorating the driver's discomfort or unrecognized performance due to visual or auditory sense.
