PURPOSE:To effectively perform the defense against the robbery of a car while preventing the overdischarge of a main power source by providing a display means displaying the operation state of a robbery preventing device toward the outside of the car and operating this display means with the electromotive force of solar cells. CONSTITUTION:A display panel 1 is installed on a package tray 102 at the rear of the back seat of a car. This display panel 1 is constituted of a light emitting element LED 3 provided nearly at the center portion of a fitting face 17 facing the inner face side of a rear window 101, solar cells 2 provided nearly at the whole remaining portion and nickel-cadmium cells 4, i.e., rechargeable dry cells which can be repeatedly charged and discharged, at the rear section of the fitting face 17. When a robbery preventing device for a car (not shown in the figure) is in the operational state, the light emitting element LED 3 serv ing as a display means is lighted by the electric power of the solar cells 2 or the nickel-cadmium cells 4, thus warning that the robbery preventing device is set in the alert state to the outside. |
