A device for opening a door (12) includes an electric motor (20) on a base (18), a slider (34) movable relative to the base (18) along a rectilinear direction (A) between a rest position and an open position, and a rod (52) pushing against the door (12) and movable relative to the base (18) and the slider (34) along the rectilinear direction (A) between a retracted position and an extracted position. An actuating element (54) resiliently pushes the rod (52) towards the extracted position. A gearwheel transmission (26, 28, 30, 60) is arranged between the electric motor (20) and a transmission device (40, 62, 64) to cause movement of the slider (34) into the open position. The gearwheel transmission (26, 28, 30, 60) includes a gearwheel 30, 60) having a non-toothed segment (32) which disengages the slider (34) from the electric motor (20) when the slider (34) reaches the open position. A recall element (50) recalls the slider (34) towards the rest position or the rod (52) towards the retracted position when the non-toothed segment (32) disengages the slider (34) from the electric motor (20). |
