To efficiently cool an exhaust gas by surely mixing outside air with the exhaust gas without increasing a length of a muffler pipe, even in a place where the muffler pipe is curved.SOLUTION: A muffler device includes an exhaust pipe connected to a motor disposed on a vehicle body so that an exhaust gas passes therethrough, a main body having an inlet from which the exhaust gas passing through the exhaust pipe flows, and an outlet from which the exhaust gas is discharged outside, and curved so that the inlet and the outlet are directed to different directions, an outside air introduction portion for introducing the outside air into the main body, and a flow dividing plate disposed on at least the curved part in the main body for dividing the exhaust gas introduced from the inlet, to the outlet.SELECTED DRAWING: Figure 6

    【課題】マフラーパイプの長さを長くすることなく、またマフラーパイプが曲がった場所でも、排気に外気を確実に混合して、排気を効率的に冷却する。【解決手段】車体に設けられた原動機に接続されて排気ガスが通過する排気管と、排気管を通過した排ガスが入る入口と排ガスを外部に排出する出口とが形成された本体であって、入口と出口とが互いに異なる方向に向くように湾曲した本体と、本体内に外気を導入する外気導入部と、本体内において少なくとも湾曲した部分に設けられ、入口から導入された排気ガスを口に至るまでに分流する分流板と、を備えている。【選択図】図6
