Zusammenfassung:To provide an exhaust collection cylinder which is excellent in exhaust noise reduction effect.SOLUTION: An exhaust collection cylinder A includes: an exhaust collection cylinder body 3 in which an exhaust port 31 is provided at a front part and a lower opening 30 enabling introduction of a flue gas into its interior is formed and which has a hollow shape therein; a predetermined partition plate part 4; a predetermined flue gas passage 5 formed rearward of and above the partition plate part 4; and a passage facing plate part 6 provided at the inner side of the exhaust collection cylinder body 3 so as face the flue gas passage 5. A first space part Sa is formed between the passage facing plate part 6 and the exhaust collection cylinder body 3. A first opening 8a, which allows the first space part Sa to serve as a first gas vibration part communicating with the flue gas passage 5, is provided at the passage facing plate part 6.SELECTED DRAWING: Figure 1 【課題】排気騒音の低減効果に優れる排気集合筒を提供する。【解決手段】前部に排気口31が設けられ、かつ燃焼排ガスを内部に導入可能とする下面開口部30を形成している内部空洞状の排気集合筒本体部3と、所定の仕切り板部4と、この仕切り板部4の後側および上側に形成された所定の燃焼排ガス流路5と、この燃焼排ガス流路5に対面するように排気集合筒本体部3の内側に設けられた流路対面板部6と、を備えている、排気集合筒Aであって、流路対面板部6と排気集合筒本体部3との相互間には、第1の空間部Saが形成され、かつ流路対面板部6には、第1の空間部Saを燃焼排ガス流路5に連通した第1の気体振動部とする第1の開口部8aが設けられている。【選択図】 図1
