To provide an inner pressure reduction device for reducing inner pressure in a snow melting roof panel by discharging a part of water vapor supplied to the snow melting roof panel out of the snow melting roof panel even immediately before completion of snow melting of the snow melting roof panel.SOLUTION: This inner pressure reduction device comprises: a water vapor discharge port 20 that is projected from the bottom surface of a snow melting roof panel; a water vapor introduction path 30 that extends from the water vapor discharge port 20; an inner pressure reduction valve 40 that is installed so as to be adjacent to the tail end of the water vapor introduction path 30; and a water vapor discharge path 50 through which the inner pressure reduction valve 40 is connected to a bypass 60.SELECTED DRAWING: Figure 5 【課題】融雪屋根パネルの融雪が完了する直前であっても、融雪屋根パネルに供給される水蒸気の一部を融雪屋根パネル外に排出することで融雪屋根パネルの内圧を緩和するための内圧緩和装置を提供する。【解決手段】融雪屋根パネルの底面に穿設する水蒸気吐き出し口２０と、水蒸気吐き出し口２０から伸びる水蒸気導入路３０と、水蒸気導入路３０の終端に隣接するように設置する内圧緩和バルブ４０と、内圧緩和バルブ４０とバイパス６０とを繋ぐ水蒸気排出路５０を備える。【選択図】図５
