Description of the Related Art Conventionally, as one type of a sealing device used under a temperature condition in which a rubber sealing part such as an O-ring cannot be used, as shown in FIG. 9, a cross section cut along a plane passing through an axis is circular. There is a so-called C-shaped seal 1, which is a hollow metal seal member having a substantially C-shape curved in an arc shape and having an opening groove 1a continuous in the circumferential direction on the inner periphery. The C-shaped seal 1 has a direction (axial direction) in which inner peripheral ends are close to each other in a seal mounting groove S formed continuously in the circumferential direction between two members 2 and 3 connected in the axial direction. The elastic member is interposed in an elastically deformed state as appropriate.
By means of the self-sealing action utilizing the fluid pressure P introduced through the valve member a, leakage of fluid from between the connecting portions of the two members 2 and 3 is prevented.
