Abstract
A hose includes an outer hose member, and an inner hose member. The outer hose member includes a first bellows-like tubular portion at least in the intermediate area in the axial direction. The inner hose member is disposed substantially coaxially in the outer hose member, includes a second bellows-like tubular portions in the area corresponding to the first bellows-like tubular portion of the outer hose member, and adapted to form a tubular air layer between the second bellows-like tubular portion and the first bellows-like tubular portion. Because of the outer hose member and the inner hose member, the hose exhibits a high flexibility, a reliable barrier ability against gasoline fuels or the like, and an improved adiabatic ability and anti-flammability for the inner hose member.
