The present invention relates to a rubber ring which allows a user to check that the internal air pressure of the rubber ring is suitable in order to be used safely. The rubber ring uses Pascal′s principle, and the appearance of the rubber ring is partially transformed so the height (thickness) of a part of the rubber ring is reduced. Accordingly, when a user presses the rubber ring by the force of an adult′s finger, the upper side and the lower side of the rubber ring touch narrowly so the user recognizes that the internal air pressure of the rubber ring is suitable.

    본 발명은 물놀이용 고무 튜브에 관한 것으로 사용자가 튜브 내부의 기압이 적당한지 확인할 수 있게함으로써 안전한 고무 튜브 사용을 위한것이다. 이러한 목적을 달성하기 위해 파스칼의 원리를 활용하고 튜브 외형의 일부를 변형하여 일부의 높이(튜브의 두께)를 줄여 일반 성인의 손가락 힘으로 눌렀을 경우 간신히 닿아(윗면과 아랫면이 접하여) 튜브 내부 기압이 적당함을 인식하는 과정을 가진다.
