BACKGROUND ART Resin fuel hoses are usually gasoline resistant,
Compound properties such as gasohol resistance, gasoline resistance, and moisture resistance are required. For this reason, the hose body 12 is made of, for example, 11 nylon, which is excellent in gasoline resistance, gasohol resistance, moisture permeability and flexibility.
Often formed of a polyamide resin such as 12 nylon.

On the other hand, these resin fuel hoses are often equipped with a protector made of an elastomer such as rubber in order to protect the hose body mainly from external factors such as mechanical and thermal.

[0006] In order to avoid interference (collision) with other outfit parts in an engine room or the like, the resin fuel hose is often bent and / or partially bent and shaped to be assembled. In particular, this tendency is increasing due to the recent increase in the density of outfitting in the engine room.

However, when a resin fuel hose equipped with a protector is used in a high-temperature atmosphere, such as in an engine room, the resin fuel hose is likely to return to a linear shape as a whole (bending is likely to occur). .).

This is because, in addition to the fact that the hose body itself is easily recovered to a linear shape, a recovery force to the linear shape due to the rubber-like elasticity of the protector acts on the hose body. The reason that the hose body itself easily recovers linearly is that the temperature in the vicinity of the resin fuel hose in the engine room is about 80 ° C., and the glass transition temperature of the material for forming the resin fuel hose (of nylon 11, which is frequently used). (40 to 50 ° C. in this case), the molecular motion of the main chain of nylon 11 becomes active, and the bending plastic strain of the hose is easily removed.

In this case, it is conceivable to use a plastic material having a glass transition temperature exceeding the upper limit of the use atmosphere as the hose body. However, the bending rigidity of the hose body becomes too high, and the workability of assembling the fuel hose is reduced. Has a negative effect.
