PROBLEM TO BE SOLVED: To provide a hose which is advantageous when reliably visualizing that the hose suffers external injury.SOLUTION: A hose 10A includes a rubber tube layer 12, first to fourth reinforcing layers 14A to 14D, first to third intermediate rubber layers 16A to 16C, a cover rubber layer 18 and a resin tube 20. The cover rubber layer 18 is laminated on the outside of the fourth reinforcing layer 14D that is an outside reinforcing layer arranged on the outermost side. The resin tube 20 is wound between the fourth reinforcing layer 14D and the cover rubber layer 18 and a coloring agent or a fluorescent agent is enclosed in the resin tube. A synthetic resin material which constitutes the resin tube 20, when an external injury which extends over the cover rubber layer 18 and the fourth reinforcing layer 14D occurs, preferably is easily broken and can be deformed while following the deformation of the hose 10A. |
