<p>A flexible hose incorporating a tube is configured so that the extension/contraction characteristics and bending characteristics of the flexible hose are not impaired at portions to which the tube inserted through the inside of the hose is bonded. A flexible hose (1) incorporating a tube is provided with: a flexible hose body (2) formed by integrally spirally winding a synthetic resin flexible strip; and a flexible tube (3) integrally joined to the inner peripheral surface of the flexible hose body (2) by an adhesive material (4). Portions (204, 22) of the inner peripheral surface of the flexible hose body (2), the portions (204, 22) being arranged on the innermost peripheral portions of the hose, has two alternately spirally arranged spiral regions (S1, S2). The surfaces of the two spiral regions (S1, S2) have different bonding properties relative to the adhesive material (4). In one spiral region (S1), the flexible hose body (2) and the flexible tube (3) are joined together, and in the other spiral region (S2), the flexible hose body (2) and the flexible tube (3) are substantially not joined together.</p> |
