<p>PURPOSE: To inexpensively integrate a composite hose provided with rubber on its outside and resin on its inside without using an adhesive to adhere the inside to the outside. CONSTITUTION: A composite hose, which is composed of a rubber made outside hose part 1 containing a first cylindrical part 11 and a resin made inside hose 2 contantaining a second cylindrical part 21, has the second cylindrical part 21 arranged with a ring member 3 on its inside circumference, while the first cylindrical part 11 has a fastening member 4 for retaining the first cylindrical part 11 in a contracted aperture state arranged with on its outside circumference, and the first 11 and the second 21 cylindrical parts are integrated together by being sandwiched between the ring member 3 and the fastening member 4. Because the first 11 and the second 21 cylindrical parts are mechanically integrated together, an adhesive becomes useless.</p> |
