1. A method for manufacturing a glass sheet, the method comprising:
- running down molten glass along both side surfaces of a molded body;
joining and integrating the molten glass just under a lower edge part of the molded body; and
pinching and downward delivering an end in a width direction of an integrated sheet-shaped glass ribbon by a roller pair, thereby drawing downward the glass ribbon and molding a center in the width direction of the glass ribbon to have an average thickness of 0.3 mm or less,wherein a pinching force is adjusted in a range in which a ratio F/T of a pinching force F (unit;
N) acting on the end in the width direction of the glass ribbon by rollers of the roller pair to an average thickness T (unit;
mm) of the center in the width direction of the glass ribbon after molding satisfies a relation expressed by the following formula (1);
10 (N/mm)≦
F/T≦
300 (N/mm)

10. A device for manufacturing a glass sheet, comprising a molded body for joining and integrating molten glass run down along both side surfaces of the molded body just under a lower edge part;
- and a roller pair for pinching and downward delivering an end in a width direction of a sheet-shaped glass ribbon integrated by the molded body, in which the glass ribbon is drawn downwardly and a center in the width direction of the glass ribbon is molded to have an average thickness of 0.3 mm or less,
wherein the device has an adjusting unit for adjusting a pinching force in a range in which a ratio F/T of a pinching force F (unit;
N) acting on the end in the width direction of the glass ribbon by rollers of the roller pair to an average thickness T (unit;
