The present invention relates to a device for reducing wind noise and vibration on fast moving elevator cars (1) consisting of externally mountable aerodynamic elements (3, 4) and a device to permit access to the car roof. The upper externally mounted element (3) with a shape similar to an ellipsoid is placed loosely on top of the elevator car (1) and held by direct mechanical means of a centering device. Recesses at the sides surround the guide roller supports (6). As a means of providing access to the car roof there is an integral lifting device which allows the upper extension element (3) to be lifted. The lower extension element (4) is constructed as a hollow body in the shape of a frame and has on its underside flaps which can be swiveled downward and which permit access to the equipment on the underside of the elevator car (1).
