<p>PURPOSE:To miniaturize a joint section by constituting a pipe with the joint section, a straight pipe and a pair of joints each formed of a spherical ring and a core and a stopper. CONSTITUTION:A joint section 13 is composed of a straight pipe 14, and a pair of joints 15 provided at both ends of this straight pipe 14. Each joint 15 is formed of a spherical ring 17 formed on the outer peripheral surface of its end part with a spherical convex surface 16, a core 19 having a first spherical concave surface 18 adapted to make slide-contact with the spherical convex surface 16, and a ring-like stopper 21 having at one end side a second spherical concave surface 20 adapted to make slide-contact wit the spherical convex surface 19 and fitted at the other end side onto a core 19. With this arrangement, no spherical convex surface 16 is located around pipes 11, 21 to be connected, it is possible to reduce the side of a flexible pipe with no restriction to the shape of the joint 15 by the outer diameter of the pipes 11, 12 to be connected.</p> |
