<P>PROBLEM TO BE SOLVED: To provide a multi-spherical joint type flexible pipe in which it is not necessary to apply a large force during assembly work and further, and if wear on a sliding contact surface occurs or the like, a frictional force can be adjusted. <P>SOLUTION: A multi-spherical joint type flexible pipe includes a plurality of spherical joint parts obtained by fitting male spherical surfaces and female spherical surfaces so as to slidingly contact. A pair of male pipes are respectively inserted from a connecting screw part side of female pipes and coupled by coupling screws, and also, a frictional force between the male spherical surface and the female spherical surface slidingly coming into contact with each other is adjusted by an adjust ring. <P>COPYRIGHT: (C)2013,JPO&INPIT |
