ABSTRACT:
An oil level detecting device for detecting an oil level in an oil storing chamber formed in a crankcase of an engine includes a fan, a power generator and an oil level determination unit. The fan is rotated by an oil flow produced by dipping up oil for lubricating the engine. In response to rotation of the fan, the generator generates a corresponding amount of electric power on the basis of which the oil level determination unit determines the oil level.
