Zusammenfassung:PROBLEM TO BE SOLVED: To obtain an evacuation structure of a discharge device which can perform evacuation while suppressing the waste of a viscous material.SOLUTION: This evacuation structure 10 of a discharge device 1 in which a follower plate 3 for closing an accommodation vessel 2 descends according to the discharge of a viscous material 6 which is accommodated in the accommodation vessel 2 comprises: an evacuation hole 11 formed at the follower plate 3; a sub-plate 12 for covering the evacuation hole 11 of the follower plate 3 from below, and arranged between the follower plate 3 and the viscous material 6; and an introduction passage 13 arranged between the follower plate 3 and the sub-plate 12, and introducing air staying in a space A2 between the sub-plate 12 and the viscous material 6 into the evacuation hole 11.SELECTED DRAWING: Figure 7 【課題】粘性材料の無駄を抑制しつつ、真空引きが可能な吐出装置の真空引き構造を実現する。【解決手段】本発明の一形態に係る吐出装置1の真空引き構造10は、収容器2に収容された粘性材料6の吐出に応じて、収容器2を塞ぐフォロワープレート3が下降する吐出装置の真空引き構造であって、フォロワープレート3に形成された真空引き用孔11と、フォロワープレート3の真空引き用孔11を下方から覆い、フォロワープレート3と粘性材料6との間に配置されたサブプレート12と、フォロワープレート3とサブプレート12との間に形成され、サブプレート12と粘性材料6との空間A2に滞留する空気を真空引き用孔11に導く導通路13と、を備える。【選択図】図7
