示装置。[Scope of claim for utility model registration] A device for displaying the gear position of an automobile, including an automatic gear shift mode switch, a manual gear shift switch,
A control unit is connected to the input side of the transmission side to which a gear stage detection member and a maintenance grounding terminal that can switch between grounded and non-grounded states, and a display element drive circuit is connected to the output side. When a shift command from the current gear is input by any of the switches mentioned above, in the case of automatic gear shifting, the current gear is displayed for a predetermined period of time from the time when the neutral position signal is input. If the shift signal is not input from the gear detecting member for that gear even though the gear is switched to a neutral position display after maintaining the above-mentioned gear position and the gear is shifted to a position other than the neutral position within the above-mentioned predetermined time. Until the signal from the gear position detection member is input,
A gear shift characterized by continuing to display the gear position before shifting, and displaying the current gear shift status as is when the maintenance ground terminal is switched to the ground position, similar to manual gear shifting. Tier display.
