Device for driving a winding drum for swimming pool cover by means of an electric motor, characterized in that it comprises a pair of thin plates (2, 3) in square, which comprise a suitable vertical main part (20, 30), each, to face each other, against one of the internal faces of the opposite side walls of the pool (p1 p2), as well as a top horizontal (21, 31), folded at right angles, adapted to rest on the horizontal edge of the side wall to which it is associated, and to be fixed to it, one (3) of these plates being provided, called "second plate ", of a guide bearing (120) of one end (12) - called the second end - of the shaft (1) of the drum and adapted to be coupled directly against the inner face of the side wall (p sub 2) to which it is associated, while the other plate (2), called "first plate", is provided with a guide bush (110) of the other end (11) - called first end - of the shaft (1) of the drum and is traversed by the latter, this first plate (2) being maintained at a distance of small width (e), which it forms a thin free space, with respect to the inner face of the side wall (p1) to which it is associated, because said electric motor (4) is mounted out of the water on the upper part of said first plate (2), and in that a movement transmission mechanism, which connects the output shaft (50) of this electric motor (4) to said first end (11) of the drum shaft (1), is arranged in the inside of said free space.
