[origin: EP2461099A1] The non-return valve (1) has valve seat (3) for floating structure (4), which is provided inside exhaust pipe mountable tubular structure (2). A circumferential groove (5) is formed at downstream of tube structure in a state bounding inner peripheral wall section (6) and outer peripheral wall section (7) in tube structure. The peripheral edge of floating structure is protruded over the radially inner peripheral wall portion, while upstream facing axial extension is extended to arrange the floating structure on valve seat in the axial direction into the circumferential groove.
