特徴とするバタフライバルブ型排気ブレーキ装置。[Claims for Utility Model Registration] A butterfly valve is installed horizontally in the exhaust pipe and has shaft parts supported by bearings on the wall of the exhaust pipe at both ends in the direction of the rotational axis. The outer end of the bearing that supports one shaft has a structure that seals the inside and outside of the exhaust pipe, and the other shaft penetrates the exhaust pipe wall and protrudes outward from the exhaust pipe and is linked to the actuator. The other shaft has a large diameter portion that can come into contact with the inner end surface of the bearing that supports the other shaft, and at least the contact portion between the one shaft and the bearing On the one hand, a passage is formed in a chamber formed by the end face of the one shaft part and its bearing part to guide exhaust gas on the high pressure side of the butterfly valve, and when the butterfly valve is in the closed position, the butterfly valve is closed. A butterfly valve type exhaust brake device characterized in that the large diameter portion is biased by the pressure of the exhaust gas in the chamber so as to come into pressure contact with the inner end surface of the bearing portion.
