2. Description of the Related Art As a conventional hose coupling structure, a structure in which a hose is inserted through a metal pipe and fixed by a clip is generally used. When fixing this branch hose structure to, for example, a vehicle body, it is desirable to fix the branch portion to the vehicle body. This is because the end of each branch hose can be fixed at once by fixing it at one place.
Therefore, conventionally, a flange portion is projected outward from the branch pipe and is attached to the attached portion via the flange portion.

When the flange portion is provided on the inner pipe, it is necessary to seal between the mold and the inner pipe at the time of molding the covering portion, which complicates the mold structure. Therefore, it is desirable that the flange portion is formed integrally with the covering portion so as to project from the covering portion. When the covering portion has a flange portion, it is desirable that the covering portion be formed of a material having an elastic modulus of 5000 kg / cm 2 or more. If the elastic modulus is smaller than this, the strength as the flange portion cannot be obtained.
