PURPOSE:To make the rear of a truck sightable at all times and improve the extent of safety, by altering angle of a rear view mirror in a motive power unit via a wire with rotation of a connecting part between the motive power unit and the truck, in case of a vehicle where both cars are connected together as being possible for horizontal rotation. CONSTITUTION:In case of a vehicle to which a motive power unit 1 such as a tractor trailer or the like and a truck 2 are connected with a pin 3 free of rotation in a horizontal direction, a pulley 12 is attached to a lower shaft 11 attached by a bearing 10 in this pin 3. And, the other end of a wire 5 whose one end is rolled on the pulley 12 is connected to a rear view mirror 6 in the motive power unit 1. Now, if the motive power unit 1 alters an angle to the truck 2 at the time of bending in a vehicle, the lower shaft 11 and the pulley 12 are rotated so that the wire is pulled whereby an angle of the rear view irror 6 is varied to some extent. Therefore, since the rear view mirror 6 reflects a rear part of the truck 2 even at the time of bending in the vehicle, a driver is able to do safety driving without anxiety. |
