• the motorized drive device 10 comprises a single driven wheel 14a, 14b.
• the driven wheel 14a, 14b is arranged opposite the drive wheel 13 and, more particularly, the axis of rotation X14a, X14b of the driven wheel 14a, 14b is aligned with the axis of rotation X13 of the drive wheel 13, in the direction of the plane P.
• the housing 43 comprises a first half-shell and a second half-shell.
• the first and second half-shells are configured to be assembled, in other words are assembled, together, by means of fasteners, in the assembled configuration of the motor drive device 10.
• the fasteners of the housing 43 may be elastic snap fasteners.
• the type of fixing elements is not limiting and can be different. These can be, for example, screw fastening elements.
• one of the first and second half-shells is a hatch, so as to allow access to the battery 12, in particular to replace the latter.
• the screening device 3 comprises two motorized drive devices 10.
• a first motor drive device 10 is configured to be held at the rod 4, in other words suspended from the rod 4, and is configured to move along the rod 4, so as to close or open a first screen 2.
• a second motorized drive device 10 is configured to be maintained on the rod 4, in other words suspended from the rod 4, and is configured to move along the rod 4, so as to close or open a second screen 2.
