To provide a vehicle managing device for performing efficient work for managing a parked vehicle in accordance with a stopping time for the vehicle.

The vehicle managing device comprises a detecting device 2 having a sensor part 7 mounted on the vehicle 1 for detecting the stop of the vehicle and a timer part 8 for measuring a passage of time since the sensor part 7 detects the stop of the vehicle 1, and an output device 3 for outputting a stopping time for the vehicle measured by the detecting device 2. This construction permits the measurement and display of the stopping time for the vehicle and discriminates whether the vehicle parked in accordance with the time is a long-time stopped vehicle or a general stopped vehicle. Thus, the need for withdrawing and replacing the vehicle is determined, resulting in efficient management of the parked vehicle.
