Claims

[Scope of Claim for Utility Model Registration] In a tail pipe muffler that enhances the silencing effect by a tail pipe provided downstream of a muffler in an exhaust system, the tail pipe is connected to an outer cylinder whose downstream side is closed with an end plate. an inner cylinder fixed concentrically within the outer cylinder, the end opposite to the end plate being closed with an end plate, and an outer exhaust passage being formed between the inner cylinder and the outer cylinder; a movable cylinder that is slidably fitted into the cylinder and closed with an end plate on the same side as the inner cylinder; and a movable cylinder that is interposed between the movable cylinder and the inner cylinder and allows the movable cylinder to slide. an exhaust discharge tube that passes through an end plate of the outer tube and is fixed concentrically to form an inner exhaust passage between the outer tube and the movable tube, the exhaust discharge tube being guided from the muffler. is discharged from the outer exhaust passage through the inner exhaust passage and the exhaust discharge tube, and the movable tube is movable by the exhaust against the spring force of the spring. pipe silencer.
