Abstract

The present invention relates to an automobile, and relates to an antenna breakage preventing apparatus for a vehicle for preventing an antenna from being damaged by a low ceiling when the vehicle enters a parking building having a low ceiling height.

In a conventional vehicle, when the driver enters a parking building with a low ceiling height while maintaining the antenna at the maximum height, the antenna may be bent or damaged by a low ceiling if the driver does not inadvertently lower the antenna.

According to the present invention, when the vehicle enters a parking building having a low ceiling height, the antenna is automatically lowered, thereby preventing the antenna from being damaged by an obstacle.
