Claims

[Claims for Utility Model Registration] (1) A butterfly-type valve body is rotatably disposed within the body, and a valve shaft protruding from both sides of the valve body is attached to a bush fitted to the side of the body. Therefore, in the exhaust switching valve for an internal combustion engine, which is rotatably supported and has an actuator linked to the end of the valve shaft protruding from the body, an annular groove is formed in a part of the outer periphery of the valve shaft, and A hole is bored at a position opposite to the annular groove, one ball is inserted across the hole and the annular groove, and the upper part of the hole is closed;
An exhaust switching valve for an internal combustion engine, characterized in that a small gap is provided around the sphere within the hole. (2) A butterfly-type valve body is rotatably disposed within the body, and a valve shaft protruding from both sides of the valve body is rotatably supported by a bush fitted to the side of the body; In an exhaust switching valve for an internal combustion engine in which an actuator is linked to an end of a valve shaft protruding from the body, an annular groove is formed in a part of the outer periphery of the valve shaft, and a position opposite to the annular groove in the body is provided. A hole is bored in the valve stem, a ball is inserted across the hole and the annular groove, and the ball is pressed into the annular groove of the valve stem by a coil spring. Exhaust switching valve for internal combustion engines.
