範囲第１項記載の内燃機関の吸入系の消音装置。[Scope of Claim for Utility Model Registration] 1. An intake system of an internal combustion engine in which an acoustic filter is formed on the side of the intake system that is open to the atmosphere by an intake duct, an air cleaner case, and a connecting tube to reduce intake noise. In the internal combustion engine, the silencer is provided with a valve body in the suction duct that operates in accordance with the negative pressure in the air cleaner case and changes the cross-sectional area of the suction duct to reduce suction noise when the engine rotates at low speeds. Silencer for the inhalation system. 2. The valve body is an elastic valve body formed by an elastic member so as to be connected to the open end of the suction duct, and curves in response to negative pressure in the air cleaner case to reduce the cross-sectional area of the suction duct. A silencer for an intake system of an internal combustion engine according to claim 1, which is variable.
