PROBLEM TO BE SOLVED: To prevent illegal action such as stopping the function of a device by pulling out a battery by locking, with a simple structure, the battery cap of an electronic device used by being attached to the sun visor of an automobile and making it difficult for those having no knowledge of the structure to easily remove the same. SOLUTION: The inner U-shaped locking groove 1d of an electronic device main body (backside cap) and the similar U-shaped locking groove 2d of a battery cap 2 are made coincident with each other in position when the battery cap 2 is closed, these are simultaneously locked by a locking attaching part 3d when the locking attaching part 3d of the tip of a visor clip 3 is inserted and the visor clip 3 is attached and thus its sliding for opening the battery cap 2 is prevented. The battery cap 2 is slid when the visor clip 3 is removed, but since this fact is not known by those having no knowledge of the structure, if the electronic device is an automobile theft preventing device for detecting an intruder, the intruder is unable to easily remove the battery or to stop an operating alarm. |
