たマフラーにおいて、ダイヤフラムにより背圧室とばね
室とに区分され該背圧室はマフラ一本体に連通しばね室
にはダイヤフラム押圧ばね、を備えた弁駆動装置をマフ
ラ一本体外部に装着し、フィルター筒におけるバイパス
孔開閉弁と上記ダイヤフラムとを上記弁駆動装置の背圧
室内背圧の上昇に応じて開閉弁が開く如く連動したこと
を特徴とする内燃機関用マフラー。A muffler with a filter cylinder inside and an exhaust bypass hole opening/closing valve device is divided into a back pressure chamber and a spring chamber by a diaphragm, the back pressure chamber is in communication with the muffler body, and the spring chamber is provided with a diaphragm pressing spring. A valve driving device is attached to the outside of the muffler main body, and the bypass hole opening/closing valve in the filter cylinder and the diaphragm are linked so that the opening/closing valve opens in response to an increase in back pressure in the back pressure chamber of the valve driving device.
