Disclosed is a card ejection mechanism comprising: a metal shell having a guide section on one side thereof; an ejection rod slidably movable within the guide section; and an ejection lever rotatable with respect to the inner surface of the metal shell and operatively connected to the ejection rod that the ejection lever rotates during actuation of the ejection rod. Ejection rod is a rectangular metal piece stamped out of a metal sheet. Guide section is composed of an inner wall which faces an inner surface of the ejection rod, outer sections facing the outer surface of the ejection rod, and a cantilever-like resilient extension provided on the same side as the outer wall sections to bias the ejection rod against the inner wall. These inner wall and outer wall sections are spaced a distance apart approximately equal to the thickness of the ejection rod. This arrangement minimizes the dimensions of the guide section and the connector incorporating the ejection mechanism, and also improves the efficiency of the ejection mechanism by providing a tight fit of the ejection rod within the guide section.

[ I claim:] [1.]1. An ejection mechanism for a card connector comprising:a stamped metal shell for receiving a card, the metal shell having a guide section at one side thereof,a stamped ejection rod slidably mounted within the guide section, the ejection rod having an inner surface, an outer surface and a thickness; anda stamped ejection lever rotatable with respect to an inner surface of the metal shell, the ejection lever operatively connected to the ejection rod such that the ejection lever is rotated during sliding of the ejection rod,wherein the guide section of the metal shell includes an inner wall facing the inner surface of the ejection rod, outer wall sections facing the outer surface of the ejection rod, wherein the inner wall and outer wall sections are spaced from each other by the thickness of the ejection rod, and a cantilevered extension formed on the guide section and adapted to bias the ejection rod against the inner wall, andthe ejection rod further includes integrally formed beads longitudinally positioned at intervals along the outer surface, whereby the beads abut against the cantilevered extension of the guide section during sliding of the ejection rod.
