<p>PROBLEM TO BE SOLVED: To improve the extension/contraction property and flexibility of a bellows portion by setting the thickness of the bellows portion thinner than the thickness of non-bellows portions in a bellows reinforced rubber hose suitably used for an air hose for a turbo charger, reinforced by fibers or a cloth, and having the bellows in the intermediate portion. SOLUTION: This bellows reinforced rubber hose is appropriately reinforced by fibers or a cloth, has the both ends formed into non-bellows portions 10 and its intermediate portion formed into a bellows portion 12 comprising crests 12a and troughs 12b, and the both-end non-bellows portions 10 are externally inserted around a mating member to be connected together. The bellows reinforced rubber hose can be formed into a straight cylinder or a curved cylinder and, in this case, the thickness of the bellows portion 12 is set relatively thinner than the thickness of the non-bellows portions 12. This constitution can improve the extension/contraction and flexibility of the bellows portion 12 and improve the vibration absorbing performance. This bellows reinforced rubber hose is manufactured by such a method as winding a cloth formed by coating rubber on its both faces or one face around a mandrel, tying its outer circumference by a bandage, and vulcanizing and forming it.</p> |
