<p>PROBLEM TO BE SOLVED: To provide a fuel hose with bellows, which is excellent in barrier property and flexibility. SOLUTION: A fuel hose is made up of a rubber-based outer hose part 1 having the first straight cylindrical parts 11, and a resin-based inner hose part 2 nearly coaxially held in the outer hose part l through a cylindrical air layer 3. The inner hose part 2 has a bellows type cylindrical part 20 and the second straight cylindrical parts 21. Further, the portion of the inner hose part 2, which shifts from the second straight cylindrical part 21 to the bellows type cylindrical part 20, has an inclined wall 2k which is inclined toward the center axis side of the inner hose part 2 so that the first trough part 20co is formed on the end side of the inner hose part.</p> |
