Abstract
A flexible tube for an exhaust pipe for an automobile includes a bellows member (10) corrugated to have alternate ridges (11) and furrows (12) along its outer periphery; outer braids (20) provided to enclose the bellows member (10); fixing caps (30) fitted onto both side ends of the outer braids (20) respectively; and a spring member (40) provided on a circumferential surface of the outer braids (20). The bellows member (10) has lower ridges (13) in its center as well as regular ridges (11) on both sides thereof to more effectively absorb over-vibration of an exhaust system of an automobile and to enhance durability of the bellows member (10).
