<p><P>PROBLEM TO BE SOLVED: To provide a hose easy to insert into the nipple of a connection fitting and hard to come off without using other components, and to provide its connection structure. <P>SOLUTION: The hose 1 comprises an inner layer rubber 2, a reinforcing layer 3 braided on the surface of the inner layer rubber 2, and an outer layer rubber 4. The braiding angle of the reinforcing layer 3 is smaller than the resting angle of the hose, and it becomes wider than the resting angle when the hose 1 is inserted into the nipple. A plurality of annular protruded portions A is provided on the surface of the nipple 11 of the connection fitting, and an annular flat portion B1 is formed on the surface of the nipple at the front end side of the hose to be inserted. Then, the annular protruded portions A and annular flat portions B2 are alternately formed. A width W1 of the annular flat portion B1 is greater than a width W2 of the other annular recessed flat portion B2 in the axial direction of the nipple. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
