摘要： An extendable and contractible flexible joint having a pair of flexible joint portions, which are bendable and fitted and connected to a connection sleeve, in a direction of a pipe axial line. An extending motion limiting portion includes a fluid chamber into which a portion of a pressure fluid in a flow path diverges and flows, and is configured to apply a fluid pressure applied to pressure receiving surfaces of the fluid chamber. An inner joint body of each of both the flexible joint portions is configured to be attachable and detachable to and from the connection sleeve, and an outer joint body and the inner joint body of each of both the flexible joint portions are configured to be attachable and detachable to and from each other.

摘要： A collar having a divided structure and surrounding a fitting connection part between a spigot portion and a socket portion in a sealed state is externally mounted over both pipe portions. A first disengagement blocking part that blocks, by contact, a relative disengagement movement beyond a certain level between the socket portion and the collar is provided at a location where the collar and the socket portion side face each other. A second disengagement blocking part provided with a retaining part in which falling-off resistance between the retaining part and an outer peripheral surface of the spigot portion increases according to a disengagement movement of the spigot portion is provided on a pipe support portion side on one end side in a pipe axis direction of the collar.
