An apparatus is for setting a communication path between a communication terminal device connected through a first network and a plurality of second networks. A grill is provided to conceal the speaker. In the event of a collision, securely engaged brakes can significantly reduce resulting vehicle acceleration, potentially avoiding a secondary collision and reducing injuries experienced by the vehicle operator and passengers. The wirings are coupled to the electrical elements to transmit the electrical signals. The attaching door portion is slightly opened toward the rear. The heat exchange medium of the present invention is a chilled gaseous fluid suspension of frozen ice particles.
