An outwardly protrudingly rib is formed on the outer portion of the crankcase which is engaged with a cut formed on the retainer member to securely position the retainer member on the crankcase. The retainer member includes a scale mark provided thereon, and the oil level sight glass permits visual observation for checking an oil level of oil held in an oil reservoir disposed at the lower portion of the crankcase.
