Abstract
A manufacturing apparatus for a thin glass sheet includes a forming member main body configured to form the thin glass sheet by fusing together, at a lower end portion of the forming member main body, streams of molten glass, which have overflown from an overflow trough to both sides of the forming member main body, under a state in which the streams of the molten glass are caused to flow down along outer surface portions having a substantially wedge shape. The manufacturing apparatus also includes a pair of covering members fitted onto both widthwise end portions of the forming member main body, respectively, the pair of covering members forming restricting wall portions for restricting widthwise spread of the streams of the molten glass flowing down along the outer surface portions of the forming member main body.
