RAMMER
PROBLEM TO BE SOLVED: To provide a rammer that is less likely to affect an engine adversely in terms of heat and induce output decline.SOLUTION: An air cleaner 8 is fitted on a top part of a rammer body, with a bracket 9 in between. An exhaust flow channel is formed between the bracket 9 and the top part of the rammer body, for discharging cooling exhaust 31 in a forward direction from an engine cooling fan disposed behind the rammer body. An air suction port 29 is disposed in a front part of the air cleaner 8. A flow regulating part 9e is disposed between the air cleaner 8 and the exhaust flow channel, the flow regulating part protruding forward of the air suction port 29. The flow regulating part 9e separates the cooling exhaust 31 from an introduction flow 33 into an air introduction part 19c.SELECTED DRAWING: Figure 10
【課題】エンジンに熱的な悪影響を与え、出力低下を招くおそれを低減したランマを提供する。【解決手段】ランマ本体の上部にブラケット９を介してエアクリーナ８を取付ける。ブラケット９とランマ本体の上部との間に、ランマ本体の後側に設けられたエンジン冷却用のファンからの冷却排風３１を前方に流出させる排風流路を形成する。エアクリーナ８の前部に空気吸込み口２９を設ける。エアクリーナ８と排風流路との間に、空気吸込み口２９より前方に突出する整流部９ｅを設ける。整流部９ｅにより、冷却排風の排出流３１と空気導入部１９ｃへの導入流３３とを分離する。【選択図】図１０
