A rear-end collision prevention device for a vehicle using the distance measuring device turning device 20 formed in this way in that the distance measuring device turning device 20 that turns the same angle as the direction change angle of the vehicle 2 in the opposite direction is used. By setting to 1A, it is possible to report a state in which a rear-end collision is likely even at the time of changing a curve or direction. Note that the distance measuring device rotating device 20 is a handle 1
9, an angle sensor 21 attached to a part that rotates in response to the operation of 9, a servomotor 22 that rotatably supports the distance measuring device 4, and data of an angle detected by the angle sensor 21 are input. A central processing unit 8A includes a control circuit that outputs a signal for rotating the servo motor 22 in the opposite direction by the angle detected by the angle sensor 21.

The third embodiment of the present invention shown in FIGS. 9 to 11 is mainly different from the first embodiment of the present invention in that the following vehicle 3 in the vicinity of the driver's seat of the vehicle 2 and in the rear is provided. The present invention is also applicable to the rear-end collision preventing device 1B having the above-described structure in that the rotating lights or the blinking display lights 15, 15 and the alarms 17, 17 are provided at the portions that can be notified. The same operation and effect as those of the embodiment can be obtained, and the mounting can be easily performed.

The fourth embodiment of the present invention shown in FIGS. 12 to 14 is different from the first embodiment of the present invention mainly in that it is retrofitted in the vicinity of the driver's seat of an automobile and is mounted on a rear panel. In the point that the rotating lights or the blinking indicator lights 15A, 15A are fixedly attached to the vehicle or the like, the vehicle rear-end collision prevention device 1C configured as described above can be used.
