Abstract
A connecting means for an exhaust pipe of a vehicle includes a bellows member made of metallic material and cylindrically corrugated for absorbing the deformation force due to the expansion and contraction of the exhaust pipe, an interlock member spirally formed on the inside of the bellows member and having spiral grooves for absorbing the deformation force due to the expansion and contraction of the exhaust pipe, a braid member for surrounding the outside of the bellows member, a cap for pressing an end part of the braid member, and a fixing member for combining the end parts of the bellows member and the interlock member. The fixing member includes a ring-shaped intermediate member one end part of which is welded under one end part of the bellows member, and the other end part of which is extended to be overlapped with the end part of the interlock member and provided with spiral protuberances to be fitted into the spiral grooves of the interlock member. Thereby, the service life of the connecting means is extended and product reliability is improved.
