Title:
HOSE JOINT
Document Type and Number:
Japanese Patent JP2008095765
Kind Code:
A
Abstract:

To surely seal a hose to a nipple by adequately diameter-shrinking a sleeve.

In the outer peripheral face of the nipple 1 opposed to the approximate center position in the axial direction of a diameter-shrunk portion 2a of the sleeve 2 across the hose H, an annular recessed groove 1b is formed extending to the peripheral direction. An elastically deformable annular seal material 4 is fitted into the annular recessed groove 1b and held therein non-movably in the axial direction. The outer peripheral end of the annular seal material 4 is protruded from the outer peripheral face of the nipple 1 and pressed against an inner peripheral face H1 of the hose H. When the sleeve 2 is diameter-shrunk, the hose inner peripheral face H1 opposed to the approximate center position in the axial direction of the diameter-shrunk portion 2a is strongly pushed against the annular seal material 4 protruded from the outer peripheral face of the nipple 1 and the hose inner peripheral face H1 is put in close contact with the annular seal material 4.
