Theft prevention device for automobiles
 An automobile theft prevention device has an idle swing mechanism including first, second, and third levers. The first and second levers are coaxially coupled to each other for angular movement and connected between an engine hook lock and an engine hood lever for opening the engine hood. The third lever is actuatable by means of a solenoid for in turn moving a connecting pin loosely fitted within slots defined respectively within the first and second levers. When an automobile door is locked, the solenoid is energized so as to move the connecting pin disposed within the slots into a position where the first lever is idly movable with respect to the second lever. Thus, the engine hood cannot be opened even if the engine hood lever is operated. The connecting pin can be moved back to its original position so as to connect the first and second levers only when the door is unlocked properly as by, for example, by means of a key for the door. Therefore, the engine hood cannot be opened even when unauthorized entry is gained by breaking a window glass panel and the engine hood lever is operated, unless the door is unlocked properly. If the engine hood lever is operated while the door is locked, an alarm is produced so as to signal the unauthorized attempt to open the engine hood.
