PURPOSE: An eyeglass frame is provided to prevent it from being put on in a crooked way by combining a protrusion in the front end of a slider unit and a groove of a lens frame and by adjusting an auxiliary eyeglass leg unit into an unfolded state. CONSTITUTION: A slider unit is able to glide about an auxiliary eyeglass leg member. The slider unit has a length that projects a base unit from the auxiliary eyeglass leg unit. The slider unit is combined with a lens frame when unfolding a primary eyeglass leg unit. The slider unit is separated from the lens frame when folding the primary eyeglass leg unit. A moving part, when folding the primary eyeglass leg unit, moves the sliding unit in a direction growing distant from the lens frame. An integrating unit integrates the lens frame into the slider with the synergy of the slider unit and the lens frame.
