Claims

[Scope of utility model registration request]

(1) Exhaust brake device equipped with a butterfly-type exhaust shutter that rotates within the exhaust pipe to open and close the exhaust gas passage when the operating shaft fitted in the through-hole of the exhaust pipe is rotated from the outside. An exhaust chamber is provided on the outer circumferential side of the exhaust pipe where the through hole is located, and has an exhaust chamber centered on the through hole and upstream of the exhaust shutter, and an exhaust chamber is provided on the operating shaft. An exhaust receiving flange located in the exhaust chamber at a predetermined distance from the peripheral wall of the pipe, and an airtight flange located outside the chamber wall at a predetermined distance from the chamber wall of the exhaust chamber, and between the airtight flange and the chamber wall. is an exhaust brake device characterized by interposing an elastic sealing material.

(2) The exhaust brake device according to claim 1, wherein the exhaust guide surface is formed on the flange of the exhaust receiver of the operation shaft.

(3) Utility model registration in which a bushing is interposed between the through hole of the exhaust pipe and the operating shaft, and an elastic sealing material is interposed between the peripheral wall of the exhaust pipe and the exhaust receiving flange of the operating shaft. An exhaust brake device according to claim 1.

(4) The exhaust brake device according to claim 1, wherein an airtight flange guide wall for the operating shaft is formed on the outer surface of the exhaust chamber wall.
