<p>PURPOSE:To prevent any knock being produced in a pin joint part from occurring, in a flexible pipe system for an exhaust pipe. CONSTITUTION:In this flexible pipe device for an exhaust pipe, each of first and second support covers 20, 30 is clamped to both first and second ends 11, 12 of a bellows 10, a pin member 40 is attached to the first support cover 20, a cap member 50 is attached to the second support cover 30, and a load receiving buffer 60 consisting of a wire mesh is interposed between the pin member 40 and the cap member 50, while in parallel with this buffer, two damping buffers 90, 90', having an elastic modulus smaller than this load receiving buffer 60 are interposed between them too. Even if crushing and settling were produced in this buffer 60 due to use for months, any lost motion thereby is absorbable by the damping buffers 90, 90', thus a knock is prevented from occurring.</p> |
