The invention relates to a roller 40 for the sunblind 20. The roller is designed to be fastened to a canvas 26 of the blind and defines an axis of rotation X. A cross-section of the roller perpendicular to the axis X :
- defines an external profile P suitable for allowing winding-up of the canvas; and
- comprises a longitudinal seat 42 formed inside the external profile P . The longitudinal seat:
- communicates with the exterior via a longitudinal slit 44 defined by two edges 440;
- comprises two separate main portions 420, inside each of which a cylinder of diameter d may be inscribed; and
- comprises an auxiliary portion 422 between the two main portions. Furthermore the two separate main portions are separated by a cusp 424 and the distance w between the cusp and each edge of the longitudinal slit is smaller than the diameter d . The invention also relates to a sunblind 20 comprising such a roller 40. |
