Apparatus adapted for mounting in a vehicle

An apparatus mounted in a vehicle having a door (24), a door detecting means (30), a driving detecting means (30), and a door control means. The door (24) has an open position and a closed position. The door detecting means (30) detects a condition of the door, and the driving detecting means (30) detects a driving condition of the vehicle, that is whether the vehicle is running or stops. The control means controls the door (24) to close and controls to announce that the door is closing, when the door is open and the vehicle is running. On the other hand, when the door is closed and the vehicle is running, the door is prevented from opening and "the door is prevented from opening" is announced. Since a clearance between the door and other parts caused by vibrations of the apparatus during running does not increase, a durability of the apparatus is high.
