<P>PROBLEM TO BE SOLVED: To provide a joint structure connecting two members so as to be freely bent and rotated. <P>SOLUTION: The joint structure 1 connecting two members 40 and 43 having flow channels for circulating a fluid or a liquid so as to be freely bent and rotated includes: a male joint 3 attached to one member 40; and a female joint 15 attached to another member 43. In the male joint 3, at an end on the side of the female joint 15, a sliding part 6 in which a part of the outer peripheral surface thereof is spherically formed is provided, and a through hole 4 communicating with the flow channel of the one member 40 is provided such that one end thereof is opened at the sliding part 6. In the female joint 15, a bearing 30 with a spherical surface which supports the sliding part 6 of the male joint 3 is provided in a part of the inner circumferential surface so as to be freely rotated, and a through hole 16 communicating with the flow channel of another member 43 is provided. This through hole 16 communicates with the through hole 4 of the male joint 3 regardless of the bending angle of the two members 40 and 43. Further, the female joint 15 can be divided into at least two sections on the dividing surface that passes through the spherical surface of the bearing 30. <P>COPYRIGHT: (C)2012,JPO&INPIT |
