本考案は各種の機械、設備或は装置等において
機密手段として溝部等に介装使用される密封弾性
Ｏ−リングの構造の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the structure of a sealing elastic O-ring that is used as a security means in a groove or the like in various machines, equipment, or devices.

う問題があつた。 As shown in FIG. 4, the conventional sealing elastic O-ring was simply composed of an endless hollow ring body 11 made of an elastic metal tube. Therefore, due to the structure of the tubular body that is continuous in the circumferential direction, there are structural constraints that make it impossible to effectively improve the elastic fatigue limit with respect to the amount of displacement when tightening under pressure within the groove during use. Therefore, when used again after being dismantled, there was a problem that the elasticity deteriorated and the airtightness was impaired.

る。 Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 3 and 5. The endless curved ring body 1 of the present invention is formed from an elastic metal strip material such as steel or stainless steel. , Width side ends 2, 2'
It has a semicircular cross-section with a free end structure, and inside the curve of the endless curved ring body 1, there is a circular arc-shaped cross-section having an outer diameter that causes crushing deformation when the top of the curve is pressed from the outside. An endless annular core 1 having an outer peripheral surface is loosely inserted, and this endless annular core is molded from an elastic metal tube material such as steel or stainless steel, or an elastic flexible material such as rubber or resin. There is.

る。 As described above, according to the present invention, the endless curved ring body 1
has a semicircular cross-sectional structure with both widthwise end portions 2, 2' being free end structures, and an endless annular core body 3 made of an elastic metal pipe material or an elastic flexible material is loosely inserted into the curved interior. Because of this structure, when used by inserting it into the annular groove 6 provided on the side surface of the base 5 as shown in FIG. 5, the ends 2, 2' hang onto the groove bottom corners 6', 6' At the same time, due to the crushing deformation of the core body 3, elastic force can be more effectively exerted, and the elastic fatigue limit with respect to the amount of displacement accompanying pressure-receiving tightening can be significantly increased. The above-mentioned effects can be fully exhibited with almost no deterioration in elasticity, and furthermore, by appropriately selecting and combining the endless curved ring body 1 and the core body 3 according to the application, the desired airtightness can be achieved. It can be adjusted to
