PURPOSE: A DMB signal blocking device for a car is provided to remove cases that a drive can not see front/rear/right/left sides due to concentration on a DMB service screen. CONSTITUTION: A DMB signal blocking device for a car includes an upper case(10), a lower case(20), a DMB signal connecting unit(50), conductive liquid(30), and a nonconductor(40). The upper case can be slid in an opposite direction to a departure direction of a car. The inside of the lower case is filled with the conductive liquid to transmit a DMB signal. The nonconductor moves to block a DMB signal connecting unit of one side among DMB signal connecting units.
