In an elevator installation a belt-like support is guided over a drive and over at least one deflecting roller. The deflecting roller includes an inner ring and an outer ring with a traction surface. The belt-like support loads the deflecting roller in a direction of loading, wherein the direction of loading is oriented substantially perpendicularly to an axis of the deflecting roller. The outer ring is mounted on the inner ring to be movable in axial direction so that in the case of a change in the direction of loading by an angle α the outer ring similarly inclines substantially through the angle α, whereby a perpendicular orientation of the direction of the loading with respect to the traction surface is substantially maintained. |
