| description | To provide an engine which can inhibit dust from reaching an oil seal even if the oil seal is exposed to the outside.SOLUTION: An engine includes: a flywheel housing 3 integrally formed with an engine body 2 and having an insertion hole 21 into which a crank shaft 13 of the engine body 2 is inserted; an oil seal 4 being provided between the crank shaft 13 and the insertion hole 21 and sealing oil in the engine body 2; and a flywheel 5 being housed in the flywheel housing 3 and connected to the crank shaft 13. The flywheel 5 is formed with an introduction passage 50 which guides outer air into a gap S1 between the flywheel housing 3 and the flywheel 5. Multiple blades 60 which are aligned in a circumferential direction of the flywheel 5 and cause the outer air introduced into the gap S1 to flow to a radial outer side of the flywheel 5 in the gap S1 are formed on a surface of the flywheel 5 which faces an inner surface of the flywheel housing 3.SELECTED DRAWING: Figure 3
【課題】オイルシールが外部に露出していても、塵埃がオイルシールに到達することを抑制できるエンジンを提供する。【解決手段】エンジンは、エンジン本体２に一体に形成され、エンジン本体２のクランク軸１３を挿通させる挿通孔２１を有するフライホイールハウジング３と、クランク軸１３と挿通孔２１との間に設けられて、エンジン本体２内のオイルを密封するオイルシール４と、フライホイールハウジング３内に収容され、かつ、クランク軸１３に接続されるフライホイール５と、を備える。フライホイール５には、フライホイールハウジング３とフライホイール５との隙間Ｓ１に外気を導く導入流路５０が形成される。フライホイールハウジング３の内面に対向するフライホイール５の表面には、フライホイール５の周方向に配列され、隙間Ｓ１に導入された外気を、隙間Ｓ１においてフライホイール５の径方向の外側に向けて流す複数の羽根６０が形成される。【選択図】図３ |
