ABSTRACT:
The invention relates to an arrangement for an exercise device. The arrangement comprises a bogie provided with running rolls for supporting a seat on a rail part. The edges of the rail part are provided with flanges so that the running rolls have room enough between the flanges. The lower flanges are thereby arranged to act as rolling surfaces for the runnng rolls when the bogie is positioned on the rail part. In order that the seat would move reliably on the rail part, a counter roll is provided on both sides of the bogie between the running rolls. The lower edge of the counter roll is arranged to be positioned at a distance from the rolling surface when the running rolls are supported on the rolling surfaces. The upper flanges are provided with counter surfaces which are supported only on the upper surfaces of the counter rolls when the running rolls rise off the rolling surfaces.
