The vehicle can be rotated to a position indicated by " START " so that the vehicle 10 can be started and the vehicle 10 can be driven.

On the other hand, the locking means 90 automatically advances the rod 92 when a predetermined time, for example, about 30 seconds has elapsed while the rod 92 is retracted to allow the rotation of the rotating plate 12. .

When the rod 92 is advanced in this manner, the end of the rod 92 is in a state of pressing one side of the rotating plate 12, and since the rotating plate 12 has already returned to the starting position, the vehicle 10 is continuously. To keep the starting state.

And when the vehicle 10 reaches the destination and the driver wants to turn off the vehicle 10, the driver reverses the key K from the "START" position to the "OFF" position. Accordingly, the rotating plate 12 also rotates in reverse with the reverse rotation of the key K. When the reverse rotation is made, the rotating plate 12 is rotated to an initial position and in contact with the end of the rod 92. The rod 92 is passed while rotating, and the rod 92 further advances by the action of the spring 98 provided in the locking means 90 to reach the guide groove 22 of the cover 20. Therefore, in the state in which the rod 92 is advanced as described above, the driver must retract the rod 92 through the drinking measurement means 40 to enable driving.
