Drag reducing device (1) for reducing aerodynamic drag at a trailing end (12) of a moving bluff body (10) comprising a first and a second panel (28,32), which are movable connected to each other to move together from a collapsed to an extended configuration. At least one bias element is provided for exerting a spring force to the first panel structure to support the movement of the panels. The bias element comprises a bendable spring rod (210). The spring rod extends along a curvature in a pre-tensioned condition in between the first and second panel from a back region B of the drag reducing device to a front region F of the drag reducing device, such that the spring rod exerts a spring force to the panel structure. The spring rod effectively supports at least one panel, while at the same time maintains a simple and reliable configuration of the drag reducing device.
