The present invention can be installed and stably in the bathtub, moreover, the provision of the ejected carbonate bathing device carbon dioxide can increase the time you can stay in the warm water from the jet part. With to accommodate the A carbon dioxide gas cylinder 3, equipped with a container 5 to support the jet part 4 for ejecting carbon dioxide gas flowing out of the carbon dioxide gas cylinder 3 in hot water in the bathtub, the carbon dioxide gas cylinder 3, the axial direction is accommodated in the collapsed position along the bottom portion 7 of the container 5, the height H3 of the lower end portion of the ejection section 4 to the container 5 in a state to be lower than the height H4 of the upper end portion of the carbon dioxide cylinder ejection part 4 and the carbon dioxide gas cylinder 3 is arranged.FIELD 7【課題】浴槽内に安定よく設置でき、しかも、噴出部から噴出された炭酸ガスが温水に滞在できる時間を長くできる炭酸入浴装置の提供。【解決手段】炭酸ガスボンベ3を収容するとともに、炭酸ガスボンベ3から流出する炭酸ガスを浴槽内の温水中に噴出する噴出部4を支持する容器5を備え、炭酸ガスボンベ3が、その軸心方向が容器5の底面部7に沿った倒れ姿勢で収容され、噴出部4の下端部の高さH3が炭酸ガスボンベの上端部の高さH4よりも低くなる状態で容器5に対して噴出部4及び炭酸ガスボンベ3が配置されている。【選択図】図7
