PROBLEM TO BE SOLVED: To develop a new internal combustion engine muffler and a motorcycle with this muffler in which the muffler can be installed in compact in a plan view, its low cost can be attained, and an efficient assembly can be carried out.SOLUTION: A muffler 1 for an internal combustion engine of this invention has a device in which a muffler main body 10 is divided into segments to form at least two or more expansion chambers 15 and sound of exhaust gas of an engine E is reduced while the exhaust gas of the engine E is fed in sequence to the expansion chambers 15. The muffler main body 10 is made in such a way that a plurality of laminated muffler element plates having a shape for realizing expansion chambers 15 and a communication passage 16 while a plate-like metallic element being worked in plastic form are assembled, all the muffler element plates are sealed at their peripheral edges to form the plurality of expansion chambers 15 that are communicated to each other by the communication passage 16.

    【課題】 本発明は、平面視においてコンパクトにマフラーを搭載でき、且つ低コスト化を図るとともに、組み立て工程の効率化をも図り得る新規な内燃機用マフラー並びにこれを具えた自動二輪車の開発を試みたものである。【解決手段】 本発明の内燃機用マフラー1は、マフラー本体10を区画して、少なくとも2室以上の膨張室15を形成し、各膨張室15に順次エンジンEの排気を導きながら、排気音の低減を図る装置において、前記マフラー本体10は、板状金属素材を塑性加工して膨張室15と連通路16とを現出させる形状を有するマフラー要素板が複数枚積層状に組み合わされ、周縁部においてすべてのマフラー要素板が密封されることにより、互いに連通路16によって連通した複数の膨張室15が形成されていることを特徴として成るものである。【選択図】図1
