<p>PROBLEM TO BE SOLVED: To provide a flexible pipe for an automobile reduced in the number of parts, simple in structure, reduced in weight and costs, and excellent in vibration durability. SOLUTION: A bellows pipe expandable in an axial direction is provided, and a blade having flexibility is arranged at an outer periphery of the bellows pips. When hook parts are partially overlapped using a member formed of a hook shape in section, helically wound and made expandable in an axial direction, a radius of the helical at a connection of an end is gradually increased, thereby being directly fixed to an inner periphery of a connection of the bellows pipe.</p> |
