Document Type and Number:
WIPO Patent Application WO/2014/057676
Kind Code:
A1
Abstract:
A pipe joint (10, 20) is provided with: a pipe body (2) which is an elastic pipe through which fluid flows; a counter-member (6, 6') to which the pipe body is mounted; a pipe body inner peripheral member (1, 1') which is in contact with the inner periphery of the pipe body and which extends further outward than an end surface of the pipe body, the pipe body inner peripheral member (1, 1') having a flange section (1a, 1'a) which is adapted to be in contact with the counter-member and also having a through-hole (1b, 1'b); and a nut (4) which is disposed on the outer periphery of the pipe body inner peripheral member and which has a female thread (4a). The counter-member is provided with a male thread (6a, 6'a) which engages with the female thread of the nut. Engaging the female thread and the male thread with each other causes the flange section to be clamped between the bottom surface of the nut and the counter-member. The pipe body inner peripheral member has a first end surface (1c, 1'c) and a second end surface (1d, 1'd), which are the two end surfaces facing each other in the axial direction. The first end surface is disposed on the pipe body side, and the second end surface is disposed on the counter-member side. The outer diameter (d1) of the first end surface is greater than the outer diameter (d2) of the second end surface.
