New mechanism for automatic closing of swing doors, which is characterized by the fact that it comprises a helical spring subjected to compression which supports, by its free front end, in the upper part of the door leaf, while the other the end supports a relatively immobile place precisely located behind the axis of rotation of said sheet, constituted by two rollers centered with symmetry with respect to the virtual alignment defined by the door leaf, concurring the particular and also characteristic circumstance that the pressure of the spring against the two mentioned rollers is exerted by the interposition of a yoke-shaped thrust block whose concavities adapt to those.
