The sliding device for a sliding panel comprises: a) a support which is shaped in or attached to the bottom portion of the panel, said support having a downwardly open upside-down U-shape; b) an oscillating arm secured to the support about a pivot axis which is horizontal and which extends transversely relative to the U-shape; c) sliding means fixed towards the free end of the oscillating arm; d) a pivoting cam which is secured to the support by a first axis of rotation and bears against the oscillating arm; and e) an adjustment screw which is fixed relative to the support and whose displacement serves to adjust the angle of rotation of the cam by means of a linkage between the cam and the adjustment screw. It may also include means for locking the oscillating arm in position relative to the support whenever the sliding means is in its high position within the support. The oscillating arm may include means for securing a cleaning pad suitable for bearing against the roller wheel and/or for extending in the form of a loop beneath the oscillating arm. |
