特徴とする排気ブレーキバルブ。 a valve body provided in an exhaust pipe of an engine and forming a part of its exhaust gas passage; a valve body disposed in the internal passage of the valve body; a rotating shaft integrally attached to the valve body; In the exhaust brake valve, each of the exhaust brake valves has a bearing member that rotatably supports a rotating shaft, and the exhaust gas passage is opened and closed by the valve body. The bearing member is press-fitted into the formed through hole, a ring-shaped recess is formed in a portion of the rotating shaft corresponding to the inner peripheral surface of the bearing member, and a pair of ring-shaped recesses are formed in the recess. A ring-shaped seal member is fitted, and a biasing means is arranged between the pair of seal members, and the outer circumferential surface of the seal member is pushed into the inner surface of the bearing member by the elastic force in the radial direction of the seal member. An exhaust brake valve characterized in that the exhaust brake valve is configured to be press-fitted to a circumferential surface and to press side surfaces of the pair of seal members to both sides of the recessed portion of the rotary shaft by the urging force of the urging member.
