Summary:To provide an exhaust top capable of discharging a gas including hydrogen from a top opening of an exhaust cylinder to atmospheric air at a vertical upper side through an exhaust port, while preventing intrusion of rain water into the exhaust cylinder.SOLUTION: An exhaust top 10 includes a body 20 having: an annular exhaust port 22 positioned at a vertical upper side with respect to a top opening 3 as an opening of a top portion 2 of an exhaust cylinder, annularly extended at a radial outer side with respect to the top opening 3, and releasing a gas including hydrogen from the top opening 3 toward the vertical upper side to atmospheric air; and an exhaust passage 24 for guiding flow of the gas from the top opening 3 to a radial outer side, and then guiding the same to the exhaust port 22 at the vertical upper side. A clearance 8 capable of discharging rain water flowing into the exhaust passage 24 through the exhaust port 22, to the outside of the exhaust cylinder, concretely, to a radial outer side of the top portion 2, is formed between an opening edge portion 4 as a part surrounding the top opening 3, of the exhaust cylinder and the body 20, in detail, an opening edge portion 44 at a vertical lower side, of a lower body 40.SELECTED DRAWING: Figure 1 【課題】排気筒内への雨水の侵入を防止ししつつ、排気筒の頂部開口からの水素を含むガスを、排気口を通して鉛直上側に大気中に放出可能な排気トップを提供する。【解決手段】実施形態の排気トップ１０は、排気筒の頂部２の開口である頂部開口３より鉛直上側であって当該頂部開口３より径方向外側において環状に延びており且つ当該頂部開口３からの水素を含むガスを鉛直上側に向けて大気中に放出する環状の排気口２２と、当該頂部開口３からのガスの流れを、径方向外側に導いた後、鉛直上側にある前記排気口２２に導く排気通路２４と、を有するボディ２０を備える。排気筒のうち頂部開口３を囲う部分である開口縁部４と、前記ボディ２０との間、詳細には、下側ボディ４０のうち鉛直下側にある開口縁部４４との間には、排気口２２を通して排気通路２４に流入した雨水を、排気筒外、具体的には、頂部２の径方向外側に排出可能な空隙８が、形成されている。【選択図】図１
