Reverse travel support device

A reverse travel support device (100) for supporting the reverse travel of a dump truck (1000) serving as a transport vehicle is provided with a rear object detection unit (2). The rear object detection unit (2) measures the distance to an object (a wheel stop (101), or the like) behind the dump truck (1000) serving as a transport vehicle. The rear object detection unit (2) is provided on the outside of a driven wheel of the dump truck (1000) serving as a transport vehicle and above the driven wheel (50) of the dump truck (1000). The reverse travel support device (100) makes it possible to prevent a wheel stop from being undetected.
