Abstract
An intake adapter is provided on an oil intake opening formed in a transaxle casing. A tightly sealed space in communication with an oil pump is provided in the lower part of the transaxle housing, formed in such a manner that it can be opened by the removal of a cover member which is secured to the transaxle casing in a freely mountable and removable manner. An oil strainer is housed in the tightly sealed space and an intake adapter is provided in communication with the tightly space and an oil sump. As a result the oil in the oil sump is taken into the intake opening of the oil strainer from the adapter, and foreign matter such as iron particles and the like is removed in a filter element and the filtered oil is supplied to an oil pump.
