    摘要： In a preliminary forming step, positioning of a glass sheet is facilitated, and generation of a hinge mark by a flapping mechanism and generation of excessively bent portions, are prevented at the same time.
    A bending method for a glass sheet comprising:
    a preliminary forming step of placing a heated and softened glass sheet on a preliminary forming supporting mold which supports edge portions of the glass sheet, and pressing the glass sheet against a forming face of the preliminary forming supporting mold in a state that the glass sheet is placed on the preliminary forming supporting mold to form the glass sheet into a desired preliminary bent shape; and
    a main forming step of transferring the glass sheet formed into the preliminary bent shape onto a main forming supporting mold which supports edge portions of the glass sheet, and pressing the glass sheet against a forming face of a main forming mold in a state that the glass sheet is placed on the main forming supporting mold to form the glass sheet into a desired final bent shape;
    wherein the preliminary forming supporting mold comprises an outer mold and an inner mold provided inside the outer mold and having a flatter glass-plate-placing face than that of the outer mold,
    the main forming supporting mold comprises a lower mold having a forming face opposed to the main forming mold;
    the preliminary forming step includes a step of transferring the heated and softened glass sheet onto the inner mold, a step of transferring the glass sheet on the inner mold onto the outer mold, a step of pressing the glass sheet placed on the outer mold against the forming face of the preliminary forming mold, and a step of holding the glass sheet formed into the preliminary bent shape by the preliminary forming mold; and
    the main forming step includes a step of transferring the glass sheet formed into the preliminary bent shape onto the main forming supporting mold, and a step of pressing the glass sheet against the forming face of the main forming mold while an under surface of the glass sheet is supported by the forming face of the lower mold while the glass sheet is placed on the main forming supporting mold.
