The invention provides a sealed container, a cover unit, a buoy, and an underwater monitoring device capable of suppressing rapid rise of internal air pressure. The sealed container is provided with: a container main body having an opening formed therein; a cover unit for closing the opening, the cover unit having a facing surface facing an outer surface of a peripheral edge portion of the opening of the container main body, and a groove surrounding the opening being formed in the facing surface; and an O-ring mounted in an elongated state on the groove, the groove including a first portion located on a side close to the opening and a second portion located on a side away from the opening and deeper than the first portion, a first gap leading from the inside of the container body to the first portion and a second gap leading from the second portion to the outside of the container body are formed between the outer surface of the container body and the facing surface of the cover unit, and the O-ring is held at the first portion and closes the first gap. The O-ring moves from the first portion to the second portion creating a gap between the outer surface of the container body and the O-ring.

    本发明提供一种能抑制内部气压的急剧升高的密闭容器、盖单元、浮标、及水中监视装置。密闭容器具有:容器主体,形成有开口;盖单元,用于堵塞开口,具有与容器主体的开口的周缘部的外表面相对的相对面,在相对面上形成有包围开口的槽;以及O形圈,以伸长状态安装在槽上,槽包括位于接近开口的一侧的第一部分、以及位于远离开口的一侧且比第一部分深的第二部分,在容器主体的外表面与盖单元的相对面之间形成有从容器主体的内部通向第一部分的第一间隙以及从第二部分通向容器主体的外部的第二间隙,O形圈保持在第一部分并堵塞第一间隙,当容器主体的内部气压升高时,O形圈从第一部分移动到第二部分,在容器主体的外表面与O形圈之间产生间隙。
