Claims10
A rubber hose with a fixing bracket, comprising:
- an inner rubber layer defining a hollow portion;
- a first braided layer formed on an outer periphery of the inner rubber layer by braiding a plurality of first multiple wound yarn materials formed by bundling a plurality of first yarn materials;
- a second braided layer formed on an outer periphery of the first braided layer by braiding a plurality of second multiple wound yarn materials formed by bundling a plurality of second yarn materials;
- an outer rubber layer formed on an outer periphery of the second braided layer, which adheres to the second braided layer;
- and
- the fixing bracket fixed on the outer rubber layer,
- wherein the first yarn material comprises a dry vinylon and the first braided layer is formed by braiding the plurality of first multiple wound yarn materials in a three-over, three-under pattern,
- wherein the second yarn material comprises a dry vinylon, and the second braided layer is formed by braiding the plurality of second multiple wound yarn materials in a two-over, two-under pattern,
- wherein the young modulus of the first yarn material and the second yarn material is not less than 17 GPa and not more than 26 GPa, and a breaking elongation of the first yarn material and the second yarn material is not less than 5% and not more than 12%, and
- wherein an adhesive force between the outer rubber layer and the second braided layer is not less than 10 N/cm and not more than 30 N/cm.
