A micromechanical component for a pressure sensor device. The component includes a substrate; a frame structure, mounted on a boundary surface of the substrate, including a diaphragm, whose inner diaphragm side borders on an interior volume, framed by the frame structure, so that when a pressure prevailing on its outer diaphragm side is above a reference pressure, the diaphragm is warped into the interior volume; and a rocker structure suspended on the inner diaphragm side, which in its operating mode is set into a rocker motion. An open gap exists between a stop face of the rocker structure and the boundary surface when a pressure prevailing on the outer diaphragm side is above the reference pressure and below a minimum operating pressure. The open gap is closed only when a pressure prevailing on the outer diaphragm side becomes greater or equal to the minimum operating pressure.
