  In the present embodiment, the length of the expansion / contraction member 35 in the expansion / contraction direction when the operator or the like moves the first expansion / contraction section 36, the second expansion / contraction section 37, or the third expansion / contraction section 38 in the expansion direction. However, the length of the elastic member 35 may be changed by mechanical means. Specifically, the glass plate conveyance support device 20 may include a stretchable member length changing device that changes the stretchable member 35 to a predetermined length in the stretchable direction before the glass plate support device 30 enters the heating furnace. . Thereby, when the kind of the glass plate 12 to be conveyed is changed, the elastic member 35 can be mechanically changed to a predetermined length according to the shape of the glass plate 12 to be conveyed. The productivity of the plate 12 can be improved.

  Moreover, when the glass plate conveyance support apparatus 20 is provided with the said expansion-contraction member length change apparatus, the change of the length of the expansion-contraction member 35 by an expansion-contraction member length change apparatus may be performed automatically. Specifically, the glass plate conveyance support device 20 may include a storage device that stores the shape of the glass plate 12 to be conveyed. In this case, the stretchable member length changing device changes the stretchable member 35 to a predetermined length in accordance with the shape of the glass plate 12 stored in the storage device. Thereby, when the kind of the glass plate 12 to be conveyed is changed, the stretchable member 35 can be automatically changed to a predetermined length according to the shape of the glass plate 12 stored in advance. The productivity of the glass plate 12 can be further improved.
