To provide an intake/exhaust configuration capable of suppressing intrusion of moisture and exhaust gas into an intake port in a carbon dioxide gas supply device using exhaust gas from a combustion mechanism.SOLUTION: A intake cylinder 110 and an exhaust cylinder 120 are provided on one surface 101 of the housing. The combustion mechanism is built in the housing and burns the fuel using the sucked air. An exhaust passage is formed between the combustion mechanism and an exhaust port 121 inside the housing. A cover member 300 is provided on one surface 101 of the housing so as to cover an intake port 111. The cover member 300 is located above the intake cylinder 110, and has a first surface 301 arranged so as to overlap the intake port 111 in a plan view of one surface 101 of the housing; a second surface 302 arranged so as to stand upright from the one surface 101 between the intake cylinder 110 and the exhaust cylinder 120; and an opening on the opposite side across the second surface 302 and the intake cylinder 110.SELECTED DRAWING: Figure 4 【課題】燃焼機構からの排気を用いた炭酸ガス供給装置において、吸気口への水分および排気の侵入を抑制することが可能な吸排気構成を提供する。【解決手段】吸気筒１１０および排気筒１２０は、筐体の１つの面１０１に設けられる。燃焼機構は、筐体に内蔵され、吸入された空気を用いて燃料を燃焼する。筐体の内部において、燃焼機構と排気口１２１との間に排気の通路が形成される。カバー部材３００は、筐体の１つの面１０１に対して、吸気口１１１を覆うように設けられる。カバー部材３００は、吸気筒１１０の上方に位置するとともに、筐体の１つの面１０１の平面視において吸気口１１１と重なるように配置される第１の面３０１と、吸気筒１１０および排気筒１２０の間に１つの面１０１から起立するように配置される第２の面３０２とを有し、かつ、第２の面３０２と吸気筒１１０を挟んで反対側が開口している。【選択図】図４
