PURPOSE: To realize a long-term stable operation even under a strong compression load by inserting a pot bottom member having a tongue-like rim portion extending axially into a press fit between the interior wall surface of a pot jacket and the peripheral wall portion of the bottom member, and forming a free end reinforced by a peripheral winding of the jacket into a flange. CONSTITUTION: An independent slit pot made of carbon fiber-reinforced plastics is composed of a pot jacket 1 and a bottom member 2. Further, the pot jacket 1 is produced by winding carbon fibers which have been saturated with plastics onto a mandrel which is removed after the plastics has hardened. Next, the bottom member 2 is made of carbon fiber-reinforced plastic and has a great thickness. The bottom member 2 is shaped to a pot having a tongue-like or apron-like rim portion 2c axially extending into a slit pot chamber, and is pasted in the pot jacket 1 as being inserted into the jacked l by a press fit. Further, a beveled rim portion 2a provides the bottom member 2 with radial resiliency, and the bottom member 2 is pressed, in addition to the press fit, to the inner face of the jacket 1 by a pressure of a medium supplied into the pot by a pump, therefore, a tight and durable connection between the bottom portion 2 and the jacket 1 can be guaranteed even when the jacket l is expanded by the medium pressure. |
