Claims

[Scope of utility model registration request]

A front exhaust pipe and a rear exhaust pipe through which exhaust gas flows are inserted into the connecting pipe from both sides, and a valve body is housed in the connecting pipe located between the front exhaust pipe and the rear exhaust pipe, and the valve body In the valve structure of the control type silencer, which is rotatable around a rotating shaft arranged in the radial direction, the outer diameter of the valve body is smaller than the inner diameter of the connecting pipe, and the front side The inner diameter of the exhaust pipe and the rear exhaust pipe are larger than that of the exhaust pipe, and the opposite ends of the front exhaust pipe and the rear exhaust pipe are cut diagonally to form inclined surfaces, and the tips of these are 1. A valve structure for a controlled silencer, characterized in that the valve structure is symmetrical about the rotation axis of the valve body, and is arranged at a position that is in the radial direction of the valve body when the valve body is closed.
