PROBLEM TO BE SOLVED: To improve visibility of a mark adjusting a rotation position of a crankshaft, in an engine wherein a closed end of a flywheel formed in a bowl shape whose outside in an axial direction is closed and arranged coaxially with the crankshaft is attached to inner faces of flange parts included in flywheel bosses fixed to a shaft end of the crankshaft. SOLUTION: A plurality of fins 54b stand on base plates 54a to constitute cooling fans 54. The base plates 54a of the cooling fan 54 is attached to an outside face of the closed end of the flywheel 48. The mark 58 for adjusting the rotation position of the crankshaft 27 is provided on the outer face close to an outer periphery of the closed end of the flywheel 48. A cutout 59 is formed in the base plate 54a of the cooling fan 54 to make the mark 58 face the outside in the axial direction. COPYRIGHT: (C)2005,JPO&NCIPI
