PROBLEM TO BE SOLVED: To provide a hyperbaric oxygen capsule that can be transported and carried in, in a divided state and installed through simple assembling work, in a large-scale capsule having such a dimension that several persons can be seated and relaxed therein, the capsule with high airtightness filled with high-pressure oxygen and the like.SOLUTION: The capsule includes: a cylindrical body to be laterally installed in a horizontal state； and a pair of cap members for closing both-end opening parts of the cylindrical body. The cylindrical body has such an outside diameter as to have a room above the heads of users seated inside thereof and is formed of a curved surface formed by outward bulging a peripheral surface of the cylindrical body. The cylindrical body is formed of divided cylindrical bodies formed by dividing the laterally-installed cylindrical body along the axial direction. Both-end cap members also include curved surfaces bulging outward, and peripheral parts fitted to the cylindrical body. The capsule is constituted by connecting the pair of cap members and the divided cylindrical bodies. An opening through which users get in and out is formed on a lateral side of the cylindrical body, and an opening/closing door having a similar curved surface to that of the cylindrical body is opened/closed in the horizontal direction along rails provided on the top/bottom of the inside face of the opening.SELECTED DRAWING: Figure 1【課題】高気圧の酸素等を充満させた気密性の高いカプセルの内部に数人が座った状態でリラックスできる大きさの大型カプセルを分割状態で運搬および搬入し、簡単な組み立て作業を経て設置することができる高気圧酸素カプセルを提供する。【解決手段】カプセルは水平状に横設する筒体と筒体の両端開口部を閉塞する一対のキャップ部材とから構成され、筒体は内部に座った使用者が頭部の上方に余裕を有する外径であって、筒体の周面が外方へ膨出した曲面で形成されると共に、横設した筒体を軸方向に沿って分割してなる分割筒体から形成され、両端のキャップ部材もまた外方へ膨出した曲面と筒体に嵌合する周部を有し、一対のキャップ部材と分割筒体を結合することによってカプセルが構成され、筒体の横側面に使用者が出入りする開口部を形成し、この開口部の内側面の上下に設けたレールに沿って筒体と同様の曲面を有する開閉扉を左右方向に開閉するようにした。【選択図】図１
